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. That's because fluorine is more electronegative than oxygen, and F is assigned an oxidation number of -1. Assign an oxidation number of -2 to oxygen (with exceptions). Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons.
