Oxidation and reduction of copper. A piece of copper metal is heated in a flame and oxidized to black copper oxide by air. The oxidized copper is reduced when placed in a hydrogen atmosphere. When removed from the hydrogen atmosphere, the metal is again oxidized. Copper oxidizes slowly in air, corroding to produce a brown or green patina.

Answer. An oxide is a chemical compound that contains the element oxygen. The oxygen in a compound will be bonded to one another element, creating a binary compound. For example, when copper metal reacts with oxygen gas, copper (II) oxide ( C u O) is formed. An oxide, therefore, contains at least one atom of oxygen.
