Silver Corrosion. Silver (Chemical symbol Ag) is a brilliant gray white metal that is quite soft and malleable. It is quite resistant to corrosion and does not oxidize easily, although it readily forms a surface tarnish of silver sulfide. A modern and comprehensive document on the subject is the second edition of the classic CORROSION BASICS textbook.
Other metals corrode. Rusting is an oxidation process. What we normally call rust is a flaky red-brown solid which is largely hydrated iron.The primary corrosion product of iron is Fe(OH)2 (or more likely FeO.nH 2 O), but the action of oxygen and water can yield other products having different colors:ther metals corrode.
