Oxidation is the process when oxygen combines with an element, changing the appearance of the element. When iron reacts with oxygen and changes to rust, this is an example of oxidation.
Oxidation state is a number assigned to an element in a compound. This number describes oxidation-reduction reactions, and balancing redox chemical reactions. The concept of oxidation states expresses the combining power exercised by elements in their compounds and is thus related to their valences.
