👉 Unoxygenized is a term used in chemistry to describe a compound that has been reduced or oxidized by oxygen. It can be defined as a substance that loses electrons and becomes more reactive, with an overall tendency towards oxidation. This process is known as reduction. For example, when copper (II) oxide (CuO) is heated, it undergoes a reduction reaction. The CuO compound gains electrons from the air, which then oxidizes the metal to form copper(III) oxide
