The Cost Factor. Get ready to cough it up. The College Board reports that the average cost of one year of in-state tuition and fees at a public four-year school is $8,655. Tack on another $9,205 in room and board costs and youâre looking at an average yearly bill of $17,860.For private school students, the situation is even worse.wo-year students get a huge break on tuition as well. According to the College Board, the average cost of tuition and fees at a two-year school is only $3,131, just over one-third of the cost for a year at a four-year public institution.
Caesium or cesium is a chemical element with symbol Cs and atomic number 55. It is a soft, silvery-gold (or, according to some, silver/colorless) alkali metal with a melting point of 28.5 Â°C (83.3 Â°F), which makes it one of only five elemental metals that are liquid at or near room temperature.
In chemistry and physics, the atomic number of a chemical element (also known as its proton number) is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an uncharged atom, the atomic number is also equal to the number of electrons. 7.5k Views Â· View Upvoters
