What does the symbol for silver Ag come from?
Silver
Silver is a chemical element with symbol Ag (from the Latin "", derived from the Proto-Indo-European "h₂erǵ": "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Silver telluride
Silver telluride is a semiconductor which can be doped both n-type and p-type. Stoichiometric AgTe has n-type conductivity. On heating silver is lost from the material.
Tincture (heraldry)
Argent is similarly derived from the Latin "argentum", "silver". Although sometimes depicted as metallic silver or faint grey, it is more often represented by white, in part because of the tendency for silver paint to oxidize and darken over time, and in part because of the pleasing effect of white against a contrasting colour. Notwithstanding the widespread use of white for argent, some heraldic authorities have suggested the existence of white as a distinct heraldic colour.
Silver acetylide
Silver acetylide is an inorganic chemical compound with the formula AgC, a metal acetylide. The compound can be regarded as a salt of the weak acid, acetylene. The salt's anion consists of two carbon atoms linked by a triple bond. The alternate name "silver carbide" is rarely used, although the analogous calcium compound CaC is called calcium carbide.
Silver cyanide
Silver cyanide is the chemical compound with the formula AgCN. This white solid forms upon treatment of solutions containing Ag with cyanide. This precipitation step is used in some schemes to recover silver from solution. Silver cyanide is used in silver-plating.
Silver (color)
The first recorded use of "silver" as a color name in English was in 1481. In heraldry, the word argent is used, derived from Latin "argentum" over Medieval French "argent".
Green
One of the more notable uses of this meaning is found in "The Wonderful Wizard of Oz". The Emerald City in this story is a place where everyone wears tinted glasses that make everything appear green. According to the populist interpretation of the story, the city’s color is used by the author, L. Frank Baum, to illustrate the financial system of America in his day, as he lived in a time when America was debating the use of paper money versus gold.Green is one of the three colors (along with red and black, or red and gold) of Pan-Africanism. Several African countries thus use the color on their flags, including Nigeria, South Africa, Ghana, Senegal, Mali, Ethiopia, Togo, Guinea, Benin, and Zimbabwe. The Pan-African colors are borrowed from the Ethiopian flag, one of the oldest independent African countries. Green on some African flags represents the natural richness of Africa.
Ammonium iron(III) sulfate
Ammonium iron(III) sulfate, NHFe(SO)·12 HO, or NH[Fe(HO)](SO)·6 HO, also known as ferric ammonium sulfate (FAS) or iron alum, is a double salt in the class of alums, which consists of compounds with the general formula AB(SO) · 12 HO. It has the appearance of weakly violet, octahedrical crystals. There has been some discussion regarding the origin of the crystals' colour, with some ascribing it to impurities in the compound, and others claiming it to be a property of the crystal itself.
Aggie (Mascot)
Aggie, sometimes referred to as the Aggie Dawg or Aggie Dog, is the official mascot of North Carolina Agricultural and Technical State University, a historically black college in Greensboro, North Carolina. Aggie can be seen representing the North Carolina A&T athletic teams on the sideline of football games at Aggie Stadium and at Corbett Sports Center during basketball games. Although the physical representation of the athletic teams is a bulldog, the term "Aggie" has a historical connection to the university's agricultural roots as a land grant university.
Emblem of the Azerbaijan Soviet Socialist Republic
The emblem features a drilling rig representing Baku's wealthy oil reservoirs and, behind it, a sunrise, standing for the future of the Azeri nation. The hammer and sickle are prominently featured above it while the red star (symbolizing "socialism on all five continents") sits at the top of the emblem, for the victory of Communism and the "world-wide socialist community of states". The outer rim features symbols of agriculture — wheat and cotton.
Lazy Magnolia Brewing Company
"Southern Gold" is Lazy Magnolia’s golden honey ale. It is brewed with locally produced honey from Ellisville, Mississippi. It is the company's second recipe designed to recognize a specific location and demographic, Hattiesburg, Mississippi - home of the University of Southern Mississippi whose mascot is the Southern Miss Golden Eagles, hence the Southern Gold name of the beer and the gold and black colors of the bottle labels and carrier.
Nar Mobile
Nar in Azerbaijani means pomegranate and that fruit is commonly used in the company's advertising which, it has been claimed, is a 'symbol of the relationship between Azerbaijan’s rich cultural heritage and modern life'. In 2011, Nar Mobile advertisements prominently featured Ell & Nikki, Azerbaijan's Eurovision Song Contest 2011 winners. On April 6, the company announced rebranding, changing the brand name as Nar, the logo to symbolize pomegranate & communication bubble, and updating creative platform as "Nar Garden."
American Silver Eagle
Despite congressional opposition to the sale of stockpiled silver through early June 1981, the House Armed Services Committee decided on June 10 to approve a Reagan administration request to sell government-owned silver beginning in fiscal year 1982 to help balance the federal budget. In July 1981, the House and Senate agreed to allow the sale of 75% of the stockpiled silver (105.1 million troy ounces) over a three-year period, and in September the price of silver fell 11% in response. Just before the first sale in October 1981, a group of politicians from Idaho—a major silver-producing state—attempted to block the auction, claiming that the sale could have a "disastrous effect" on the United States silver mining industry in general and several Idaho silver mining companies in particular. On December 3, 1981, Senator James A. McClure (R-Idaho) proposed an amendment (S.UP.AMDT.738) to the Department of Defense appropriation bill () to end the government's sale of silver "until the President, not later than July 1, 1982, redetermines that the silver authorized for disposal is excess to the requirements of the stockpile." The appropriations bill was signed into law (Public Law 97-114) with the amendment intact, effectively stopping the further sale of stockpiled silver.
Coat of arms of Saskatchewan
On the gold chief is a lion passant or leopard, a royal symbol of England. (English lions are usually gold with red tongues and claws; however, the default colours for a heraldic lion on a gold field are red with blue tongue and claws.) The three gold sheaves of wheat, or garbs, represent the province's agriculture; the heraldic sheaf of wheat has become a generalized symbol of the province.
Agriculture in Saskatchewan
Notable people who have contributed highly to the development the agricultural industry in Saskatchewan have been inducted into the agricultural hall of fame.
The Coat of arms of Saskatchewan features three gold sheaves of wheat, or garbs, represent the province's agriculture; the heraldic sheaf of wheat has become a generalized symbol of the province. The gold lower half of the Flag of Saskatchewan symbolizes the southern, prairie wheat-fields. The provincial symbol is a sheaf of wheat and is generally used to identify government programs and organizations.
Isotopes of silver
Naturally occurring silver (Ag) is composed of the two stable isotopes Ag and Ag with Ag being the more abundant (51.839% natural abundance). Twenty-eight radioisotopes have been characterized with the most stable being Ag with a half-life of 41.29 days, Ag with a half-life of 7.45 days, and Ag with a half-life of 3.13 hours.
Gamma Sigma Delta
The Society's emblem is a key, which bears the words "The Honor Society of Agriculture" with the Greek letters ΓΣΔ as its insignia. These three letters stand for the Greek words, "Gaea", "Syndesmos" and "Demeter", which in turn were chosen for their symbolism, which is further explained as, ""The binding together of earth, the mother of all, and the practice of agriculture, and the arts relating thereto for the welfare of mankind.""
Silver(II) fluoride
AgF is a white crystalline powder, but it is usually black/brown due to impurities. The F/Ag ratio for most samples is < 2, typically approaching 1.75 due to contamination with Ag and oxides and carbon.
Silver
Silver(II) complexes are more common. Like the valence isoelectronic copper(II) complexes, they are usually square planar and paramagnetic, which is increased by the greater field splitting for 4d electrons than for 3d electrons. Aqueous Ag, produced by oxidation of Ag by ozone, is a very strong oxidising agent, even in acidic solutions: it is stabilized in phosphoric acid due to complex formation. Peroxodisulfate oxidation is generally necessary to give the more stable complexes with heterocyclic amines, such as [Ag(py)] and [Ag(bipy)]: these are stable provided the counterion cannot reduce the silver back to the +1 oxidation state. [AgF] is also known in its violet barium salt, as are some silver(II) complexes with "N"- or "O"-donor ligands such as pyridine carboxylates.
Silver
Silver(I) sulfide, AgS, is very readily formed from its constituent elements and is the cause of the black tarnish on some old silver objects. It may also be formed from the reaction of hydrogen sulfide with silver metal or aqueous Ag ions. Many non-stoichiometric selenides and tellurides are known; in particular, AgTe is a low-temperature superconductor.
Emblem of the Transcaucasian Socialist Federative Soviet Republic
The emblem is based loosely on the state emblem of the Soviet Union. It incorporates designs from each of the three major groups that combined in the Transcaucasian SFSR, the Armenians, Azeri and Georgians, and unusually features Islamic art and communist elements side by side. The latticework in the star itself bespeaks the former coat of arms of Georgia from 1918-1921 and adopted again from 1991-2004; the crescent represents the Muslim Azeris, on a background depicting the national symbol of the Armenians, Mount Ararat. The rising sun stands for the future, the star as well as the hammer and sickle for the victory of communism and the "world-wide socialist community of states".
Francis Xavier Vira Arpondratana
The silver (argent) is the symbol of the transparency, then of the Truth and Justice, fundamental dowries of the pastoral solicitude of the Bishop.
Soldier Support Institute
Symbolism – The green background represents the green of the countryside near Fort Benjamin Harrison, Indiana, the original location of the organization. The torch and heneage knot are adapted from the shoulder-sleeve insignia of the original unit's parent organization at the time the insignia was adopted, the U.S. Army Administrative Schools Center. Gold and silver represent the enduring value of the knowledge imparted by the schools that comprise the Institute. The two white stars are symbolic of guidance and leadership. The Latin motto means instructing or "Teaching the Soldier".
Ordo Aurum Solis
The Ogdoadic Tradition stems from the Mediterranean mystery religions of ancient Greece as well as the Theurgic practices of the priesthoods of Ptolemaic Egypt. Its signature symbol is the Eight-pointed Star of Regeneration, an emblem signifying the Regeneration of the Soul and Divine Inspiration. Its philosophy and practices appear in the works of early Hermetists and the teachings of the Neoplatonic schools of Alexandria, Apamea, and Athens in Late Antiquity. According to its initiates, the father-figure of the Tradition is Hermes Trismegistus.
Mercury (element)
Hg is the modern chemical symbol for mercury. It comes from "hydrargyrum", a Latinized form of the Greek word ὑδράργυρος ("hydrargyros"), which is a compound word meaning "water-silver" (from ὑδρ- "hydr-", the root of ὕδωρ, "water," and ἄργυρος "argyros" "silver") – since it is liquid like water and shiny like silver. The element was named after the Roman god Mercury, known for his speed and mobility. It is associated with the planet Mercury; the astrological symbol for the planet is also one of the alchemical symbols for the metal; the Sanskrit word for alchemy is "Rasavātam" which means "the way of mercury". Mercury is the only metal for which the alchemical planetary name became the common name.
Decarboxylative cross-coupling
Silver being in the same group as copper, Pd–Ag(I) bimetallic systems are inherently similar to Pd–Cu catalytic systems. However, silver salts are better suited for protodecarboxylation of carboxylic acids than their copper equivalents, allowing milder reaction conditions in Pd–Ag cycles relative to Pd–Cu cycles.
Ag(I) catalyzed monometallic systems have also been reported. Their proficiency (relative to copper) is likely attributed to lower electronegativity and greater expansion of d-orbitals, which promote decarboxylation of the substrate.
One limitation of this catalyst combination is that the silver salts will form insoluble silver halides, forcing the reaction to require a stoichiometric amount of Ag if halides are present. This obstacle was overcome by Goossen "et al." in 2010 by using aryl triflates, and catalytic reaction with aryl sulfonates has also been reported.
Samani
The growing of samani () - green sprouting wheat - is the most sacred Novruz ceremony as the herald of spring. Sprouting samani symbolises sowing and a rich harvest, it represents grain, bread, increase and abundance.
Grain and abundance is a pledge of life, existence, the most vital material necessity for life. People have always grown samani from wheat, barley, peas, lentils or other grains in copper dishes; they have always revered it and rejoiced at its sprouting.
Army Reserve Sustainment Command
Symbolism: The shield is adapted from the Army Materiel Command (AMC) and highlights the direct support to AMC and its subordinate elements. The colors signify the Command's missions. Bronze, buff and red indicate the sustainment/support role as well as the tie to the logistics community. Blue is a nod to the support mission for Defense Contract Management Agency as well as AMC. The four stars represent strength, experience, knowledge, and support. The arrow, flaring up from the base, represents the focus to bring the strength and teamwork of both officers and enlisted to one focus or point to support the mission of many.
Gold is emblematic of honor and high ideals. The colors and configuration of the disc refer to Army Materiel Command and support to its subordinate elements. The four stars represent the strength, experience, knowledge, and support. The compass points and rayed lines on the back disc signify a compass rose and highlight the worldwide mission of the Command. The arrow, flaring up from the base, represents the focus to bring the strength of both officers and enlisted to the one focus or point to support the mission of many. It also underscores the Command's motto which translates to "One Sustains Many." The green of the motto scroll points out the United States Army and its total readiness.
Sigma Alpha
The sorority was named Sigma Alpha for "Sisters in Agriculture." The sorority's official colors are emerald and maize, the mascot is the baby bull, the official flower is the yellow chrysanthemum, and the symbolic jewel is the emerald. The motto is "Cultivating Professional Women in Agriculture". The objective of Sigma Alpha is to promote its members' roles in all facets of agriculture.
National Service Scheme
The symbol for the NSS has been based on the giant Rath Wheel of the world-famous Konark Sun Temple (The Black Pagoda) situated in Odisha, India. The wheel portrays the cycle of creation, preservation and release. It signifies the movement in life across time and space, the symbol thus stands for continuity as well as change and implies the continuous striving of NSS for social change. The eight bars in the wheel represents 24 hours of a day. The red colour indicates that the volunteer is full of young blood that is lively, active, energetic and full of high spirit. The navy blue colour indicates the cosmos of which the NSS is tiny part, ready to contribute its share for the welfare of the mankind. It stands for continuity as well as change and implies the continuous striving of NSS for social transformation and uplift.
Northern Administrative Okrug
The narrow silver belt symbolizes the Moscow Canal, which passes through the territory of the administrative okrug. The two golden wings symbolize air traffic and the Sheremetyevo International Airport. The silver eight-pointed star represents Polaris and points to the northern location of the administrative okrug in Moscow. The gold and silver sails of the ship symbolize the river transport. The silver horses represent the racetrack. Finally, the silver Corinthian style columns represent the porticos of the Central Moscow Hippodrome.
American Biotech
The company utilizes SilverSol nano-catalytic technology in their products. SilverSol Technology has twenty plus safety reports and test series as well as the first ever double blind, FDA cleared, human ingestion toxicity study done on any silver product. SilverSol silver particles are Ag404 molecules. The term "Sol" is a chemical designation of a pure mineral permanently suspended in water where the mineral’s charge is transferred to the entire body of water. The technology is also known as Silver Hydrosols.
Atlanta Silverbacks FC
The Silverbacks official colors were red, black, silver, and white, and the club logo featured those four colors prominently. On January 23, 2013 a new logo was announced. The club's name was inspired by Willie B., a gorilla who was a main attraction of Zoo Atlanta until his death in February 2000.
Agdenes
The coat of arms is from modern times. They were granted on 30 August 1991. The arms show a field of ermine under a red chief. The ermine field symbolizes the fur farming in the municipality. As ermine is also a royal symbol, it symbolises the fact that in historical times the local overlords ("jarls") and kings have resided in the village. The red chief across the top was chosen to represent the importance of strawberry farming in the municipality.
2010 ASEAN University Games
The official mascot of the 2010 ASEAN University Games is a hill tribe youth named Nong Hug. The name Hug was chosen for the mascot, because Hug means Love in Northern Thai language which is also the beginning of unity and harmony. In English, the word Hug defines as to embrace or hold one's arms to show the love shared and to hug each other. "Nong" is the Thai word for young man, or little brother. The combination of love and hug as shown in the red cloth wrapped around Nong Hug's waist represents the existence of love when being hug for not just people of the host country Thailand but also participating countries of the games from Southeast Asia.
The Games opening ceremony was held at the Maejo University gymnasium on 15 December 2010, 16:14 (TST). The ceremony began with the athletes from participating nations paraded into the university's gymnasium led by flag bearers. After that, the Thai National Anthem was played as the national flag of Thailand was raised by students from the military school. This was followed by a hilltribe dance performance to honor the country's King and Queen for aiding and providing the hilltribes people services such as crop replacement and outlet for handicrafts, and the speeches from Chiang Mai Deputy Governor Naruemol Palwat, Secretary General of the Office Higher Education Commission and President of the Organizing Committee Dr. Sumet and President of the ASEAN University Sports Council, Honorable Dato Professor Omar Osman. Chinaworn Bunyakiart, the Minister of Education for Thailand later gave his speech as well and went on to declare the games opened by the ceremonial gong three times, symbolizing good luck, health and prosperity. After that, Nonthiya Jiewbangpa, the singer of the 1995 Southeast Asian Games theme song, sang the games theme song, "We are one", and the athlete and referee oath were taken. Then three athletes, 2 footballers from Maejo and a karate exponent from Rajaphat University carried in the torch into the stadium and pass it on to Chiang Mai University student Thanyaluck Chotipiboon who carried the torch to light a giant Yi Peng lantern cauldron to start the games. The ceremony concluded with a Lanna cultural dance performance.
Silver
Twenty-eight radioisotopes have been characterized, the most stable being Ag with a half-life of 41.29 days, Ag with a half-life of 7.45 days, and Ag with a half-life of 3.13 hours. Silver has numerous nuclear isomers, the most stable being Ag ("t" = 418 years), Ag ("t" = 249.79 days) and Ag ("t" = 8.28 days). All of the remaining radioactive isotopes have half-lives of less than an hour, and the majority of these have half-lives of less than three minutes.
Silver oxide
AgO features linear, two-coordinate Ag centers linked by tetrahedral oxides. It is isostructural with CuO. It "dissolves" in solvents that degrade it. It is slightly soluble in water due to the formation of the ion Ag(OH) and possibly related hydrolysis products. It dissolves in ammonia solution to give soluble derivatives.
A slurry of AgO is readily attacked by acids:
where HX = HF, HCl, HBr, or HI, HOCCF. It will also react with solutions of alkali chlorides to precipitate silver chloride, leaving a solution of the corresponding alkali hydroxide.
Alpha Gamma Sigma (fraternity)
Alpha Gamma Sigma (ΑΓΣ), commonly known as Ag Sig or AGS is a national social and professional agricultural fraternity that exists on eight campuses. The mission statement of Alpha Gamma Sigma is "Preparing men for life by: coming together as scholars, living as brothers, becoming leaders of tomorrow."
Proustite
Proustite is a sulfosalt mineral consisting of silver sulfarsenide, AgAsS, known also as light red silver or ruby silver ore, and an important source of the metal. It is closely allied to the corresponding sulfantimonide, pyrargyrite, from which it was distinguished by the chemical analyses of Joseph L. Proust (1754–1826) in 1804, after whom the mineral received its name.
Emblem of the Armenian Soviet Socialist Republic
The emblem prominently features Mount Ararat, regarded as the national symbol of Armenia. The grapes shown immediately beneath Ararat represent the traditional Biblical account of the first vineyard that Noah planted upon his descent from his ark as a sign of rebirth of humanity. The inner rim on the sides of the grapes includes wheat, symbolic of the land and natural resources of Armenia. Above Mount Ararat is the hammer and sickle with the red star behind it. Printed on the outer rim are the words "Armenian Soviet Socialist Republic" in Armenian (Հայկական Սովետական Սոցիալիստական Հանրապետություն "Haykakan Sovetakan Sots’ialistakan Hanrapetut’yun") while in the center outer rim is the motto "Workers of the world, unite!" in both Armenian (Պրոլետարներ բոլոր երկրների, միացե՜ք "Proletarner bolor yerkrneri, miats’ek’!") and Russian (Пролетарии всех стран, соединяйтесь! "Proletarii vsekh stran, soyedinyaytes′!").
African Union
The emblem of the African Union consists of a gold ribbon bearing small interlocking red rings, from which palm leaves shoot up around an outer gold circle and an inner green circle, within which is a gold representation of Africa. The red interlinked rings stand for African solidarity and the blood shed for the liberation of Africa; the palm leaves for peace; the gold, for Africa's wealth and bright future; the green, for African hopes and aspirations. To symbolise African unity, the silhouette of Africa is drawn without internal borders.
Golborne High School
The school badge comprises a green shield, quartered by the red cross of St George of England. In each quarter of the shield are symbols representing the industry in the area- the black diamond representing coal mining, the crossed shuttles of the weaving industry, and a sheaf of wheat symbolising local agriculture. The fourth symbol is the red rose of Lancashire, although technically the school now lies in Greater Manchester since local government re-organisation in 1974.
Eisenschmitt
The symbol made of the two interlocking letters I and S stands for “Isen-Schmitt”, the old Eisenschmitt foundry mark from the 16th century. The tinctures gules and argent (red and silver) are the Malbergs’, under whose lordship Eisenschmitt lay until feudal times came to an end. The horizontal zigzag stripe (“fess dancetty”) on the dexter (armsbearer’s right, viewer’s left) side is the sign of the old County of Manderscheid and a reference to the village’s former allegiance thereto. On the sinister (armsbearer’s left, viewer’s right) side are a hammer and tongs, symbols of the iron industry that lasted centuries, and from which the municipality also got its name.
Sterling silver
The black silver sulfide (AgS) is among the most insoluble salts in aqueous solution, a property that is exploited for separating silver ions from other positive ions.
Philadelphia Gold and Silver Index
The Philadelphia Gold and Silver Index is an index of thirty precious metal mining companies that is traded on the Philadelphia Stock Exchange. The index is represented by the symbol "XAU", which may be a source of some confusion as this symbol is also used under the ISO 4217 currency standard to denote one troy ounce of gold. The Philadelphia Gold and Silver Index and the NYSE Arca Gold BUGS Index are the two most watched gold indices on the market.
AEA Silver Dart
From 1891, Bell had begun experiments at Baddeck and Hammondsport to develop motor-powered heavier-than-air aircraft. By 1908, the success of the AEA was seen in a series of ground-breaking designs, culminating in the "Silver Dart". By the time the "Silver Dart" was constructed in late 1908, it was the Aerial Experiment Association's fourth flying machine. One of its precursors, the "June Bug", had already broken records. It won the "Scientific American" Trophy for making the first official one mile (1609 m) flight in North America.
Aurora consurgens
"Aurora consurgens" is a commentary on the Latin translation of "Silvery Waters" by Senior Zadith (Ibn Umayl). It also refers to the "Song of Songs", especially in its last (7th) parable (de confabulatione dilecti cum dilecta), which draws closely on it, in main parts paraphrasing it. Unusual for a work of this type, the text is accompanied by about thirty-seven fine miniatures in watercolour. The illustrations are representations of alchemical symbols depicted in human or animal form. For example, mercury is depicted as a serpent, gold as the sun and silver as the moon. These illustrations incorporate some of the earliest Greek alchemical symbols known, found in the "Authentic Memoirs" of Zosimos of Panopolis.
Agmark
The term agmark was coined by joining the words 'Ag' to mean agriculture and 'mark' for a certification mark. This term was introduced originally in the bill presented in the parliament of India for the "Agricultural Produce (Grading and Marking) Act".
Georgia State University
The school's coat of arms is registered in the College of Arms in London. The Latin motto means, "Truth is strong and will conquer" (or alternatively, "Truth is valuable and shall overcome"). The panther holds the symbol of education, with the quill in red to symbolize the fire in Atlanta's city emblem. The gold coin indicates the university's beginnings as a business school. The crown august is a representation of the Stone Mountain granite. The center flame is an eternal flame in honor of the first president, George Sparks, and represents flames of scholarship and the burning of Atlanta.
Flag of Voronezh Oblast
According to Resolution #292-II adopted by the Voronezh City Duma on September 26, 2008 for the city flag, the argent (silver) of the jug and water is symbolic of nobility, purity, justice, generosity and peace. Gules (red) of the field is the colour for vital force, fortitude, festivity, beauty and labour which characterises the city of Voronezh as an industrially developed centre. The golden of the rocks signifies harvest, exuberance and fertility, symbolising a well developed agrarian sector of economy. At the same time the gold represents nobility, respect, honour, mental power, light and spirituality.
Emblem of the Association of Southeast Asian Nations
The colours of the emblem are specified as follows:The design was based on rice, the staple food and probably the most important crop for the Southeast Asian people. Since ancient times, rice is always associated with prosperity, welfare and wealth. This corresponds to the vision of the founding fathers of ASEAN to create a peaceful and prosperous region in Southeast Asia. The current design is derived from the previous emblem, also featuring a bundle of "padi" rice stalks bound together in unity. The different is the rice stalks was six to represent the five founding nations of ASEAN (Indonesia, Malaysia, Philippines, Singapore, Thailand) added with Brunei (joined on 8 January 1984). The old emblem background was white. The name "asean" was placed under the rice stalks in the centre of a yellow circle with cyan circumference. Both the circle border and "asean" letters were in cyan, while the rice stalks was in golden brown.
Silver
White silver nitrate, AgNO, is a versatile precursor to many other silver compounds, especially the halides, and is much less sensitive to light. It was once called "lunar caustic" because silver was called "luna" by the ancient alchemists, who believed that silver was associated with the moon. It is often used for gravimetric analysis, exploiting the insolubility of the heavier silver halides which it is a common precursor to. Silver nitrate is used in many ways in organic synthesis, e.g. for deprotection and oxidations. Ag binds alkenes reversibly, and silver nitrate has been used to separate mixtures of alkenes by selective absorption. The resulting adduct can be decomposed with ammonia to release the free alkene.
Silver nanoparticle
Samsung’s description of the Ag nanoparticle generating process seems to contradict its advertisement of silver nanoparticles. Instead, the statement indicates that laundry cycles. When clothes are run through the cycle, the intended mode of action is that bacteria contained in the water are sterilized as they interact with the silver present in the washing tub. As a result, these washing machines can provide antibacterial and sterilization benefits on top of conventional washing methods. 
Samsung has commented on the lifetime of these silver-containing washing machines. The electrolysis of silver generates over 400 billion silver ions during each wash cycle. Given the size of the silver source (two “gum-sized” plate of Ag), Samsung estimates that these plates can last up to 3000 wash cycles.
Silver arsenate
Silver arsenate is an inorganic compound with the formula AgAsO. It has been used in qualitative analysis to distinguish between phosphate(AgPO is yellow) and arsenate(V) solutions.
Herefordshire
The red colouring ("gules") of the shield is taken from the arms of the City of Hereford. The red colour also represents the red earth of Herefordshire. The silver and blue wave across the centre of the shield represents the River Wye. The lions that form parts of the arms, crest and supporters are also taken from Hereford's arms. The agricultural produce of Herefordshire is represented by the bull's head, fleece, hops and apples. The talbot dog comes from the heraldry of the Talbot family, Marcher Lords of Shrewsbury and also from that of Viscount Hereford.
Silver trifluoromethanesulfonate
Silver trifluoromethanesulfonate, or silver triflate is the triflate (CFSO) salt of Ag. It is a white or colorless solid that is soluble in water and some organic solvents (most interestingly, benzene). It is a reagent in the synthesis of organic and inorganic triflates.
84th Field Artillery Regiment
Symbolism: Shield: The shield is red for Artillery. The saltire is taken from the State flag of Alabama, the birthplace of the Regiment. The winged spur signifies that the unit was mounted. Crest: The two Distinguished Unit Citations awarded the organization during World War II are symbolized by the crescent for French Tunisia and the raguly chevron for the bridgehead at Remagen. The irregular upper edge of the chevron alludes to the attempted destruction of the Ludendorff Bridge by the retreating enemy. The fountain is used to represent the organization's action along the Meuse River; and the fleur-de-lis symbolizes the unit's action in the Ardennes.
Silver
Under standard conditions, silver does not form simple carbonyls, due to the weakness of the Ag–C bond. A few are known at very low temperatures around 6–15 K, such as the green, planar paramagnetic Ag(CO), which dimerizes at 25–30 K, probably by forming Ag–Ag bonds. Additionally, the silver carbonyl [Ag(CO)] [B(OTeF)] is known. Polymeric AgLX complexes with alkenes and alkynes are known, but their bonds are thermodynamically weaker than even those of the platinum complexes (though they are formed more readily than those of the analogous gold complexes): they are also quite unsymmetrical, showing the weak "π" bonding in group 11. Ag–C "σ" bonds may also be formed by silver(I), like copper(I) and gold(I), but the simple alkyls and aryls of silver(I) are even less stable than those of copper(I) (which tend to explode under ambient conditions). For example, poor thermal stability is reflected in the relative decomposition temperatures of AgMe (−50 °C) and CuMe (−15 °C) as well as those of PhAg (74 °C) and PhCu (100 °C).
Silver
By far the most important oxidation state for silver in complexes is +1. The Ag cation is diamagnetic, like its homologues Cu and Au, as all three have closed-shell electron configurations with no unpaired electrons: its complexes are colourless provided the ligands are not too easily polarized such as I. Ag forms salts with most anions, but it is reluctant to coordinate to oxygen and thus most of these salts are insoluble in water: the exceptions are the nitrate, perchlorate, and fluoride. The tetracoordinate tetrahedral aqueous ion [Ag(HO)] is known, but the characteristic geometry for the Ag cation is 2-coordinate linear. For example, silver chloride dissolves readily in excess aqueous ammonia to form [Ag(NH)]; silver salts are dissolved in photography due to the formation of the thiosulfate complex [Ag(SO)]; and cyanide extraction for silver (and gold) works by the formation of the complex [Ag(CN)]. Silver cyanide forms the linear polymer {Ag–C≡N→Ag–C≡N→}; silver thiocyanate has a similar structure, but forms a zigzag instead because of the sp-hybridized sulfur atom. Chelating ligands are unable to form linear complexes and thus silver(I) complexes with them tend to form polymers; a few exceptions exist, such as the near-tetrahedral diphosphine and diarsine complexes [Ag(L–L)].
Ribbon of Saint George
The symbolism of the orange and black (or yellow and black) is thought to represent fire and gunpowder of war, or the death and resurrection of Saint George, or the colours of the original Russian imperial coat of arms (black eagle on a golden background). Another theory is that it is, in fact, German in origin, derived from the or and sable stripe patterns found on the heraldry of the House of Ascania, from which Catherine II originated, or the County of Ballenstedt, the house's ancient demesne.
Group 12 element
Hg is the modern chemical symbol for mercury. It comes from "hydrargyrum", a Latinized form of the Greek word Ύδραργυρος ("hydrargyros"), which is a compound word meaning "water-silver" (hydr- = water, argyros = silver) — since it is liquid like water and shiny like silver. The element was named after the Roman god Mercury, known for speed and mobility. It is associated with the planet Mercury; the astrological symbol for the planet is also one of the alchemical symbols for the metal. Mercury is the only metal for which the alchemical planetary name became the common name.
Silver sulfate
The synthesis of silver(II) sulfate (AgSO) with a divalent silver ion instead of a monovalent silver ion was first reported in 2010 by adding sulfuric acid to silver(II) fluoride (HF escapes). It is a black solid that decomposes exothermally at 120 °C with evolution of oxygen and the formation of the pyrosulfate.
Noah's Ark silver coins
The Noah's Ark silver coins are Armenian bullion coins issued since 2011. They are available in various sizes with a fine weight between ¼ ounce and 5 kg in silver of 999/1000 fineness. The coin has a nominal value of 500 Dram (1 ounce) and is a legal tender in Armenia, although it is not minted there but is produced by the Leipziger Edelmetallverarbeitungs GmbH, an affiliate company of Geiger Edelmetalle. The motif of the coin remains constant, similar to other bullion coins such as the Canadian Silver Maple Leaf, the Vienna Philharmonic, or the American Silver Eagle.
Silver oxide
Silver(I) oxide is the chemical compound with the formula AgO. It is a fine black or dark brown powder that is used to prepare other silver compounds.
Agnico Eagle Mines Limited
In 1953, five struggling mining companies joined together to become Cobalt Consolidated Mining, which would last until 1957, when the company changed its name to Agnico Mines. "Agnico" is derived from the periodic table of elements using the symbols for silver (Ag), nickel (Ni) and cobalt (Co).
In 1963, visionary Paul Penna became the president of Agnico Mines, and he eventually oversaw the merger of Agnico Mines with Eagle Mines Ltd, a successful gold exploration company, enabling the development of Eagle's Joutel mining complex. The newly formed company became Agnico Eagle Mines Limited.
Hayes and Harlington Urban District
The green field stood for the district's agricultural background and the amenities of the Green Belt. The silver pall was derived from that in the arms of the See of Canterbury. In 790 King Offa granted lands in Hayes to the Archbishop of Canterbury, and for more than seven centuries the place was closely associated with the See. Among the Archbishops who sometimes resided at Hayes was Anselm, who is commemorated by St. Anselm's Church. The limbs of the pall also suggested runways and together with the wings referred to nearby London Airport. The cog-wheels stood for industry in general and the lightning flashes to the electrical industries in particular.
The circlet of brushwood and deer referred to the name 'Hayes' which is derived from 'Hesa', which was a brushwood enclosure used as a trap for deer. The seax (Saxon sword) came from the arms of Middlesex and the Saxon crown referred to the fact that in that period parts of the district were royal property.
Coat of arms of Perth
The shield of the arms contains the red cross of St. George as shown on the flag of England. The top-left quarter of the shield and the supporters are black swans which are common to the area and significant to the original name of the Swan River Colony. Black swans are also shown on the Western Australian arms and flag. The fourth quarter of the shield is taken from the arms of Perth, Scotland, the city after which Perth is named. The helm is a gold brickwork crown, indicating these arms are for a municipality, and the supporting swans wear similar crowns around their necks. The motto, "Floreat", is Latin for "flourish" or "prosper".
North Carolina A&amp;T Aggies football
"Aggie", sometimes referred to as the "Aggie Dawg (or "Aggie Dog"), and his female counterpart "Aggietha" ("pronounced Agatha") represent the Aggies as the official A&T mascots.
The two can be seen on the sideline of football games at Aggie Stadium. Although, the physical representation of the athletic teams is a bulldog, the term "Aggie" has a historical connection to the university. The term "Aggie" has long been used to refer to students who attend agricultural schools. Hence the reason the university adopted the nickname "Aggies" when the school was founded in 1891.
Jade Magnet
Joining the TiE Program also helped Manik and Sitashwa raise initial seed funding, with the help of which they launched the platform, rebranded by the name of Jade Magnet, on 15 October 2009. The name was changed from CreADivity since it was observed that people found it difficult to pronounce the name and place the brand. The company's new name was derived from Jade - a precious stone with sacred connotations in many cultures, and Magnet that signifies an ability to pull towards itself anything that comes close to it. The design of the company's logo itself was the result of a crowdsourcing exercise, where multiple designers created more than 15 design options. The logo that was finally chosen symbolizes high-value by juxtaposing “a” and “g” together (“Ag” is the scientific name of silver), with the "g" falling slightly to represent the magnetic force of gravity.
Mărțișor
George Coşbuc stated that Mărțișor is a symbol of fire and light, and of the Sun. The colours and the traditional silver coin hung from the thread are associated with the sun. White, the colour of silver, is a symbol of power and strength. The round form of the coin is also reminiscent of the Sun, while silver is associated with the Moon. These are just a few of the reasons why the Mărțișor is a sacred amulet.
Silver
Silver fulminate, AgCNO, a powerful, touch-sensitive explosive used in percussion caps, is made by reaction of silver metal with nitric acid in the presence of ethanol. Other dangerously explosive silver compounds are silver azide, AgN, formed by reaction of silver nitrate with sodium azide, and silver acetylide, AgC, formed when silver reacts with acetylene gas in ammonia solution. In its most characteristic reaction, silver azide decomposes explosively, releasing nitrogen gas: given the photosensitivity of silver salts, this behaviour may be induced by shining a light on its crystals.
Dolgesheim
The silver eagle is the charge borne by the Counts of Leiningen and represents their former lordship over Dolgesheim. The lily sceptre stands for purity and the Church, while the staff of oath stands for the municipality’s duty and loyalty. The plough stands for the ancient working of the land and the municipality’s links with agriculture.
Gold (color)
Gold is the oldest color associated with Arizona State University and dates back to 1896 when the school was named the Tempe Normal School. Gold signifies the "golden promise" of ASU. The promise includes every student receiving a valuable educational experience. Gold also signifies the sunshine Arizona is famous for; including the power of the sun and its influence on the climate and the economy. The student section, known as The Inferno, wears gold on game days.
Isotopes of silver
Isotopes of silver range in atomic weight from 92.950 u (Ag) to 129.950 u (Ag). The primary decay mode before the most abundant stable isotope, Ag, is electron capture and the primary mode after is beta decay. The primary decay products before Ag are palladium (element 46) isotopes and the primary products after are cadmium (element 48) isotopes.
American Silver Eagle
The reverse was designed by John Mercanti and portrays a heraldic eagle behind a shield; the eagle grasps an olive branch in its right talon and arrows in its left talon, echoing the Great Seal of the United States; above the eagle are thirteen five-pointed stars representing the Thirteen Colonies. The reverse is inscribed with the phrases "UNITED STATES OF AMERICA", "1 OZ. FINE SILVER~ONE DOLLAR", and "E PLURIBUS UNUM" (on the banner that the eagle holds in its beak), as well as the mintmark if applicable.
Emblem of the Lithuanian Soviet Socialist Republic
The emblem is an example of so-called "socialist heraldry". It featured symbols of agriculture (oak branches and wheat). The rising sun stood for the future of the Lithuanian nation, the red star as well as the hammer and sickle for the victory of communism and the "world-wide socialist community of states". The banner bore the USSR State motto ("Proletarians of all countries, unite!") in both Russian and Lithuanian ("Visų šalių proletarai, vienykitės!"). The initialism of the Lithuanian SSR is shown only in the Lithuanian language – LTSR, for "Lietuvos Tarybų Socialistinė Respublika". The coat of arms differed little from those of Estonian, Latvian, Moldavian or other soviet socialist republics.
Silver azide
Silver azide is the chemical compound with the formula AgN. This colorless solid is a well-known explosive.
Gold
The symbol "Au" is from the , the Latin word for "gold". The Proto-Indo-European ancestor of "aurum" was "*h₂é-h₂us-o-", meaning "glow". This word is derived from the same root (Proto-Indo-European "*h₂u̯es-" "to dawn") as "*h₂éu̯sōs", the ancestor of the Latin word Aurora, "dawn". This etymological relationship is presumably behind the frequent claim in scientific publications that "aurum" meant "shining dawn".
Digermyne
Noticing that the a(π) bonding orbital in digermynes has the ability to act as the π-electron donor, ArGeGeAr can react with AgSbF to form [AgArGeGeAr]SbF at -40 C. [AgArGeGeAr] has a C axis through the silver atom which is perpandicular to the CGeGeC plain and the midpoint of the Ge-Ge bond. The silver atom is coordinated by two Ge atoms and two arenes from Dipp groups of the bulky protecting groups. The bond between GeGe moiety and Ag is dominated by the interaction between the HOMO of ArGeGeAr and 5s and 5p orbitals of Ag, which claims the σ-character of the interaction, while the π-character can be explained by the relative weak interaction of Ag 4d orbital with π* orbital (LUMO+1). Therefore, it has been suggested that [AgArGeGeAr] is a hybrid of π-complex and a metallacyclopropene-like σ-complex.
Alterkülz
The red and silver checkerboard pattern in the lower half of the escutcheon refers to the village’s former allegiance to the “Hinder” County of Sponheim and the "Amt" of Kastellaun. As early as 1283, Alterkülz was being mentioned in a few Sponheim documents ("cule", "kultze"). The charge here, the hammer and sledge, recall the iron ore mining that was undertaken at the Grube Eid (mine) from 1780 (as it is established in historical records) until the First World War. The ears of wheat stand for agriculture, once every villager’s occupation. Many lordships were enfeoffed here, the Sponheims, the Koppensteins, the Hunolsteins and the Bourscheids. The springing billygoat represents the outlying centre of Wehr, where the "Wehrer Bick" live, "Bick" being a local form of the German "Böcke" (“bucks”, “male animals”, and thus in this case, “billygoats”). The billygoat also graces the new town hall’s roof.
Ali Ai Ligang
Ali-Aye-Ligang is a spring festival associated with agriculture, specially with the beginning of the Ahu paddy cultivation. It is celebrated by the Mising or Mishing an indigenous Assamese community of Assam, India. The festival marks onset of sowing seeds. The name of the festival is made up of three terms, 'Ali', legumes, 'Aye', seed and 'Ligang', to sow.
Search Guard Successor Foundation
His surname is from the surname of Japanese imperial family member and Buddhist , who left for India to try to find Nirvana after resigning the title of Crown Prince. However, he went missing while sailing. His given name is pronounced like the chemical symbol for silver: Ag.
SWAG (silver, wine, art and gold)
SWAG is an asset class comprising silver, wine, art and gold, identified by economist Joe Roseman in his 2011 "Investment Week" article, "SWAG: The Industry's Latest Acronym". He describes these as transportable and easy to store physical assets with no income stream (and so no exposure to income tax) and no incumbent debt, whose performance appears unrelated to the performance of equity markets; and he notes that none of these factors would be affected by sovereign default.
Alpha Sigma Tau
Alpha Sigma Tau's colors are emerald green and purest gold, while its flower is the yellow rose, its jewel is the pearl, and its symbol the anchor. The sorority does not have an official mascot. The badge is a black, kite-like polygon with a golden ΑΣΤ inscribed on the enamel, bordered by gold inlaid with small pearls. Members who perform further duties may order different badges with different jewels on the badge's four points – ruby for volunteers, yellow topaz for NPC delegates, and emerald for National Council members and officers, while the national president's badge has a double border of gold inlaid with pearls.
Silver World Award
The award consists of a silver medallion enameled in blue with meridian lines, stars and the universal emblem of the BSA suspended from a red and white striped ribbon worn around the neck. The medallion represents the global scope of the award.
Argentium sterling silver
Argentium silver is a brand of modern tarnish-resistant silver alloys, containing either 93.5% or 96% silver. Argentium alloys replace some of the copper in the traditional sterling silver alloy (92.5% silver + 7.5% copper) with the metalloid germanium. Argentium's patents refer to percentages of Zinc and Boron being present in Argentium silver. Both Argentium alloys exceed the standard required for hallmarking as sterling silver and Argentium silver 960 meets the standard for hallmarking as Britannia silver (95.84% silver).
AAG Gold Medal
The AAG Gold Medal is the highest award given by the international Association of Applied Geochemists (AAG). It recognizes recipients' lifetime achievements, or significant contributions to geochemistry and its applications. The medal is minted with the name of the recipient and the year of the award from two troy ounces of silver bullion.
Silver Legion of America
A white-supremacist, antisemitic group modeled after Hitler's Brownshirts, the paramilitary Silver Legion wore a silver shirt with a blue tie, along with a campaign hat and blue corduroy trousers with leggings. The uniform shirts bore a scarlet letter "L" over the heart: an emblem meant to symbolize Loyalty to the United States, Liberation from materialism, and the Silver Legion itself. The blocky slab serif "L"-emblem was in a typeface similar to the present-day Rockwell Extra Bold. The organizational flag was a plain silver field with such a red "L" in the canton at the upper left.
Kfar Silver
The village was founded in 1957 on the initiative of the Zionist Organization of America, and was named after Abba Hillel Silver. It was planned by Meir Horman. In March 2008 it was hit by a BM-21 fired from the Gaza Strip.
African National Congress
The ANC flag comprises three equal horizontal stripes – black, green and gold. Black symbolises the native people of South Africa, green represents the land and gold represents the mineral and other natural wealth of South Africa.
Silver
Silver and gold have rather low chemical affinities for oxygen, lower than copper, and it is therefore expected that silver oxides are thermally quite unstable. Soluble silver(I) salts precipitate dark-brown silver(I) oxide, AgO, upon the addition of alkali. (The hydroxide AgOH exists only in solution; otherwise it spontaneously decomposes to the oxide.) Silver(I) oxide is very easily reduced to metallic silver, and decomposes to silver and oxygen above 160 °C. This and other silver(I) compounds may be oxidized by the strong oxidizing agent peroxodisulfate to black AgO, a mixed silver(I,III) oxide of formula AgAgO. Some other mixed oxides with silver in non-integral oxidation states, namely AgO and AgO, are also known, as is AgO which behaves as a metallic conductor.
Fronhofen
The silver charge in base, the mount of three (called a "Dreiberg" in German heraldry) and the lion standing thereupon are drawn from the 1773 seal once used by the "Schultheißerei". The lion refers to the former landholders, the Counts of Simmern and the Elector of the Palatinate. The abbot’s staff refers to the lordly estate of the Augustinian canons of Ravengiersburg, from which the municipality gets its name, “lordly estate” being "Fronhof" in German.
Silver
The word "silver" appears in Anglo-Saxon in various spellings, such as "seolfor" and "siolfor". A similar form is seen throughout the Germanic languages (compare Old High German "silabar" and "silbir"). The chemical symbol Ag is from the Latin word for "silver", "argentum" (compare Ancient Greek ἄργυρος, "árgyros"), from the Proto-Indo-European root *"h₂erǵ-" (formerly reconstructed as "*arǵ-"), meaning "white" or "shining": this was the usual Proto-Indo-European word for the metal, whose reflexes are missing in Germanic and Balto-Slavic. The Balto-Slavic words for silver are quite similar to the Germanic ones (e.g. Russian серебро ["serebro"], Polish "srebro", Lithuanian "sidabras") and they may have a common origin, although this is uncertain: some scholars have suggested the Akkadian "sarpu" "refined silver" as this origin, related to the word "sarapu" "to refine or smelt".
Silver coin
Other than collector's silver coins, silver bullion coins are popular among people who desire a "hedge" against currency inflation or store of value. Silver has an international currency symbol of XAG under ISO 4217.
.ag
In addition to its original intended use as a country code, the .ag domain has been marketed for use for agriculture-related sites, and for sites referencing the atomic symbol for silver, Ag. It also has a potential use for other domain hacks for English words that end in -ag. The Heritage Foundation uses .ag for URL shortening (herit.ag).
Silver nitride
Silver nitride is an explosive chemical compound with symbol AgN. It is a black, metallic-looking solid which is formed when silver oxide or silver nitrate is dissolved in concentrated solutions of ammonia, causing formation of the diammine silver complex which subsequently breaks down to AgN. The standard free energy of the compound is about +315 kJ/mol, making it an endothermic compound which decomposes explosively to metallic silver and nitrogen gas.
Arenrath
The escutcheon’s silver parting (described in the German blazon as a "Stufenbalken", and apparently having no equivalent in English heraldic language) and the begging bowl are said to be references to the local church’s patron saint, Alexius, who is represented in legend as a beggar under a staircase. The wheat ears stand for agriculture and the field tincture vert (green) is a reference to the municipality’s name, Arenrath, which itself refers to “Arend’s clearing”. Green stands for woods and fields while the gules-argent (red-silver) combination is a reference to the village’s former allegiance to the Electorate of Trier.
Garnet
The word "garnet" comes from the 14th‑century Middle English word "gernet", meaning 'dark red'. It is derived from the Latin "granatus," from "granum" ('grain, seed'). This is possibly a reference to "mela granatum" or even "pomum granatum" ('pomegranate', "Punica granatum"), a plant whose fruits contain abundant and vivid red seed covers (arils), which are similar in shape, size, and color to some garnet crystals.
Silver
Silver also has more negative cultural meanings: the idiom thirty pieces of silver, referring to a reward for betrayal, references the bribe Judas Iscariot is said in the New Testament to have taken from Jewish leaders in Jerusalem to turn Jesus of Nazareth over to soldiers of the high priest Caiaphas. Ethically, silver also symbolizes greed and degradation of consciousness; this is the negative aspect, the perverting of its value.
AG
A&G, AG, Ag or ag may refer to:
Silver
Isotopes of silver range in relative atomic mass from 92.950 u (Ag) to 129.950 u (Ag); the primary decay mode before the most abundant stable isotope, Ag, is electron capture and the primary mode after is beta decay. The primary decay products before Ag are palladium (element 46) isotopes, and the primary products after are cadmium (element 48) isotopes.
