... In binary compounds of metals and non-metals the oxidation number of metals is always positive while that of non-metals is negative. Eg. In NaCl, the oxidation number of sodium is + 1 and that of chlorine is 1. In compounds formed by the combination of non-metallic atoms, the atom with higher elec ...
