Similar to iron and aluminum, the element copper undergoes the process of oxidation, if it is exposed to air. Copper metal reacts with oxygen, resulting in the formation of copper oxide, which appears green in color. It is to be noted that copper does not react with water.The outer green layer, formed after the oxidation of copper, is known as patina. Unlike other destructive oxidation, patina acts as a protective layer.This is the reason as to why, copper is considered as an important metal, resistant to corrosion.t is to be noted that copper does not react with water.
