Silver (Ag)
Silver (Ag)
Silver has been known since ancient times. It occurs natively and in argentite, horn silver, lead, lead-zinc, copper, gold, copper-nickel, and other ores.
Pure silver is a lustrous and brilliant white. A little harder than gold, it is malleable and ductile, with high electrical and thermal conductivity and low contact resistance. Silver is stable in pure air and water and tarnishes with exposure to ozone, hydrogen sulfide, or air that contains sulfur.
The alloy sterling silver is used for jewelry and silverware, and silver is important in photography, dental alloys, solder and brazing alloys, electrical contacts, and high-capacity batteries. Silver itself is not toxic, but most of its salts are poisonous.
