This soft white metal is moderately resistant to corrosion, though far less so than gold Though it is found as native metal or as a sulfide ore in its own right, it is a common impurity in galena, the sulfide of lead, and because such large quantities of lead are produced, galena is the principle commercial source of silver as well as lead.
