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) where it is +2. Oxidation number is the charge left on the atom of interest, when all the bonding electrons are removed with the charge devolved to the more electronegative atom. The oxidation number is zero if the element does not loose or gain any electrons. Our channel.
