What is the oxidation number formula?

Oxygen has normally an oxidation number -2. For example, CuO → Cu⁺² + O⁻², here the oxidation number of O is -2. The oxidation number of an ion is equal to its charge. The algebraic sum of the oxidation numbers of all the atoms in a compound must be zero and the oxidation number of many atomic ions equal to its charge.
