Silver is a naturally occurring element. It is found in the environment combined with other elements such as sulfide, chloride, and nitrate.Pure silver is "silver" colored, but silver nitrate and silver chloride are powdery white and silver sulfide and silver oxide are darkgray to black. Silver is often found as a byproduct during the retrieval of copper, lead, zinc, and g ores.
