For ions composed of only one atom, the oxidation number is equal to the charge on the ion. The largest oxidation number exhibited by an element depends on its outer electronic configuration. The oxidation state (number) of an atom within a molecule is usually considered to be the formal charge on the atom if hypothetically all of the molecules are composed of ions. Since Br 2 is a stronger oxidant than I 2, it oxidises S of S 2 O 3 2-to a higher oxidation state of +6 and hence forms SO 4 2-ions.
