For instance, at 1 atm and the temperature of burning magnesium, nitrogen will combine with magnesium to form Mg3N2. According to rule 4, the sum of the oxidation number on all atoms must equal the charge on the species, so we have the simple algebraic equation. 1. State as to why (a) Alkali metals show only +1 oxidation state. Thus it is reduced, while Mg is reducing agent and it is oxidised because the oxidation number of Mg increases (0 to +2) while that of N decreases (0 to -3). But elevate the temperature and the pressure and nitrogen turns reactive. Oxidation states can be used to understand electron transfer in these reactions.
