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 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.
