WebSo the O atom gets all the shared electrons and H gets none. H normally has one valence electron; now it has none. So its oxidation number is +1. The O atom gets two electrons from each O-H bond, plus its four lone-pair electrons, for a total of eight electrons. It normally has six valence electrons, so its oxidation number is -2. WebIn all these examples, the total oxidation state of the molecule adds up to 0. On top of that, there is a general trend that O has an OS (Oxidation State) of -2 (usually) and H has an OS of +1 (again, usually).
