Copper oxidizes whereby it turns Blue / Green. Oxidation is a phenomenon whereby an element loses electrons (and/or hydrogen) on interacting with another element. There are many examples of oxidation, which we observe in our day-to-day life.t 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.
