How does copper react with oxygen

Web9 rows · the more vigorously it reacts with other substances the more easily it loses … WebThe 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.
