What is Silver?
Atomic Number: 47
Silver and silver compounds have many uses. Silver is very ductile and malleable, being just slightly harder than gold. It is the best known as the highest conductive metal of electricity at common temperatures and pressures. It is also the best reflector of visible light, but silver coated mirrors must be given a protective coating to prevent them from tarnishing.
Silver is often used with gold to give gold a greater hardness. White 9 carat gold contains 62.5% silver and 37% gold, while 22 carat gold contains 8.4% silver (and possible copper) and 91% gold. Silver, like gold, can be shaped and transformed at room temperature by hammering.
