Each Br atom has an oxidation number of zero.
No. The oxidation numbers of nitrogen and oxygen do not change.
In chemistry, the oxidation state is a number assigned to an element as an indicator of the degree of oxidation of an atom in a chemical compound."The charge an element would have if it were an ion "Oxidation state is the same as the oxidation number. It is an indicator of the degree of oxidation of an atom in a chemical compound.
