Metal > SilverAg - Silver Properties | Isotopes | Compounds The precious metal silver was known to the ancients. Our students encounter silver nitrate when studying reactions and as Tollen's reagent to test for aldehydes. The electrochemistry of silver is also investigated. Uses of silver and its compounds include ornamentation, electronics and antibacterial agents. Atomic number 47 Density, g/mL 10 .5 Atomic weight,u 107 .868 Melting point, K 1234 Bonding radius, A 1 .34 Boiling point, K 2436 Atomic radius, A 1 .75 Heat of vaporization, kJ/mol 250 .58 Ionization Potential, V 7 .576 Heat of fusion, kJ/mol 11 .3 Electronegativity 1 .93 Specific heat, J/gK 0 .235 The oxide is amphoteric. Crystal are face centered cubic. Electron config. : [Kr] 4d10 5s1 The Element, Silver, is a heavy metallic element with a brilliant white luster. The chemical symbol for silver, Ag, derives from its Latin name, argentum, meaning "white and shining"--an apt description. The metal has been used as currency since ancient times, both in the mass (bullion) and in the form of coins. Silver shares Group IB of the periodic table with gold and copper. Silver, gold, platinum, and mercury are together categorized as noble metals because they do not oxidize readily when heated, nor do they dissolve in most of the inorganic acids. Because of silver's value it is also categorized as a precious metal, as are gold, platinum, iridium, and palladium. Besides being a monetary metal, silver has also long been used for making jewelry, solid silver or silver-plated objects such as eating utensils. Photography, catalysts, brazing alloys, dental amalgam, bearings and electronics make up the major commercial uses of silver. Photography used to be the primary use of silver, however since the advent of digital and non film based photography, silver's industrial uses now constitute the primary demand for the precious metal, accounting for 40% of silver used, with photography accounting for 22%, and jewelry and silverware makes up for 31% of the silver consumption.
