What Is The Oxidation State Of Na In Na2O?

In Na2O, sodium (Na) has an oxidation state of +1. This is because oxygen (O) has an oxidation state of -2 and the overall compound has a neutral charge, so the oxidation state of the two sodium atoms must add up to +2 to balance the -4 oxidation state of the two oxygen atoms. Therefore, each sodium atom in Na2O has an oxidation state of +1.
