Oxidation states simplify the process of determining what is being oxidized and what is being reduced in redox reactions. However, for the purposes of this introduction, it would be useful to review and be familiar with the following concepts:. To illustrate this concept, consider the element vanadium, which forms a number of different ions e. The positive oxidation state is the total number of electrons removed from the elemental state. Each time the vanadium is oxidized and loses another electron , its oxidation state increases by 1. If the process is reversed, or electrons are added, the oxidation state decreases. The ion could be reduced back to elemental vanadium, with an oxidation state of zero. If electrons are added to an elemental species, its oxidation number becomes negative. This is impossible for vanadium, but is common for nonmetals such as sulfur:.
