Precipitates of thiosulfate ions and colours. Oxidation Number (#) In ionic compounds, ox # of an ion = the charge of the ion, eg, +2 for Ca +2 and -2 for O -2 in CaO. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component. The development of a water oxidation catalyst has been a demanding challenge in realizing water splitting systems. In polar compounds, ox # of an atom = the charge it would have if it were an ion (if all electrons in each bond are assigned to the more electronegative* atom), eg, +2 for C and -2 for O in CO.
