Oxidation Number: When two or more different elements come together to form a chemical compound, there is oxidation (electron loss) and reduction (electron gain) of the component atoms involved. Its powerful oxidizing properties are suggested by the oxidation number of +2 for the oxygen atom instead of its normal −2. In a neutral molecule, the sum of the oxidation numbers of all atoms is zero. Oxygen almost always has an oxidation number of -2, except in peroxides (H 2 O 2 ) where it is -1 and in compounds with fluorine (OF 2 … Oxygen usually exhibits an oxidation number of –2, but exceptions occur in peroxides, superoxides, and when oxygen combines with fluorine. 6. The element is toxic in nature and very corrosive, hence it is not easier to store fluorine. Fluorine's oxidation number is -1.In an ion, the oxidation number is equal to its charge.
