Rusting is also called as the process of slow eating of metals. It takes place in various metals and has no fixed composition. Basically, it is the reaction of some gas and the moisture in the atmosphere with the metal which leads to rusting. Commonly we relate rusting with iron which reacts with oxygen in the atmosphere and forms iron oxide. Also, silver rusts too leading to its black colour.
