When a metal is atacked by its surrounding air , moisture , acid etc it is said to be corroded . The process is called corrosion.

Electrochemical corrosion of metals occurs when electrons from atoms at the surface of the metal are transferred to a suitable electron acceptor or depolarizer. Water must be present to serve as a medium for the transport of ions.
