Similar to iron and aluminum, the element copper undergoes the process of oxidation, if it is exposed to air. If the atmosphere consists of high humidity moisture, then this process is faster. The copper metal reacts with oxygen, resulting in the formation of an outer layer of copper oxide, which appears green or bluish-green in color. This layer is known as the patina. Unlike other destructive oxidation processes, the patina acts as a protective layer, and it does not cause any weakness in the metal.
