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.
In a compound the sum of oxidation states of the elements contained is zero.E1 + E2 + ... = 0If you know the oxidation states of the elements E1... you can calculate the oxidation state of the element E2.
