Wiki User. The oxidation number of oxygen is almost always -2, unless it is in a superoxide, peroxide, bonded to fluorine, or with itself. This would be Fe2O3. Usually, oxygen has an oxidation of -2 that is unless in a compound with peroxides or halogens. Tags Oxidation Numbers Subjects.

Oxidation number of fe2o3

This page explains what oxidation states oxidation numbers are and how to calculate and use them. 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. Notice that the oxidation state isn't always the same as the charge on the ion that was true for the first two cases but not for the third. The positive oxidation state is the total number of electrons removed from the elemental state. It is possible to remove a fifth electron to form another ion. 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.
