Element Description

Known since ancient times, it is believed man was separating silver from lead as early as 3000 B.C. Pure silver is a lustrous, white metal, more ductile and malleable than any other metal, excluding gold. Silver is the best reflector of visible light known until air causes it to tarnish. In pure air and in water, it is stable. Silver has the highest electrical and thermal conductivity of all metals.
