The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. Thus ... Oxygen usually has an oxidation number of -2 .


Assign an oxidation state (or oxidation number) to an atom in a molecule or ion. ... The oxidation state of oxygen in its compounds is -2, except for peroxides like H2O2, and .... This is the normal oxidation state of group VA: N, P, As, Sb, Bi.


Usually the oxidation no of oxygen is -2 and the oxidation no of hydrogen is +1 in a compound.


The oxidation number of oxygen in compounds is usually -2, but it is -1 in peroxides. The sum of the oxidation numbers of all the atoms in a neutral compound is 0.
