Oxidation number chemguide
http://www.chemguideforcie.co.uk/section91/learningfj.html WebThe sum of the oxidation numbers must equal 0 because it is a neutral compound. Sodium is an alkali metal so its oxidation number is +1. There are two sodium atoms, so the oxidation number of sodium adds up to +2. Oxygen has an oxidation number of -2, and because there are three oxygen atoms, the oxidation number of oxygen adds up to be -6.
