WebOxidation state. In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom if all of its bonds to different atoms were fully ionic. It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound. Conceptually, the oxidation state may be positive, negative or zero.

WebThe stability of oxidation state depends mainly on electronic configuration and also on the nature of other combining atom.
