The oxidation number of chromium in CrO 3 is to be determined. Concept introduction: Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species. The oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.
