The three oxygen atoms have a combined oxidation of -6, corresponding to their electromagnetic charge and the lone nitrogen has a charge, or oxidation number, of +5. H = + 1. above should be known to you since these are among oxidation number rules : This is a redox reaction. 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. Most commercially available nitric acid has a concentration of 68% in water. Fluorine's oxidation number is -1.In an ion, the oxidation number is equal to its charge.
