The oxidation number of oxygen in H2O2 is -1. The state of oxidization directly corresponds to the change in the number of electrons when one atom joins other atoms in a...
Exceptions to this are that hydrogen has an oxidation state of −1 in hydrides of
active metals, e.g. LiH, and oxygen has an oxidation state of −1 in peroxides, e.g.
The less electronegative one is given a positive oxidation state. Remember that
fluorine is the most electronegative element with oxygen second.
