Chem.
the state of an element or ion in a compound with regard to the electrons gained or lost by the element or ion in the reaction that formed the compound, expressed as a positive or negative number indicating the ionic charge of the element or ion. Also called oxidation number.

oxidation state,
Chemistry. the state of an element or atom in a compound with respect to the number of electrons it has lost or gained, expressed as a positive or negative number indicating the ionic charge of the atom and equal to its valence. In most of their compounds, the oxidation state of oxygen is ―2 and that of hydrogen is + 1.
