Oxidation number of nitrogen is important to decide to whether NO 2 can be oxidized or reduced. The two nitrogen atoms are in different oxidation states. Assigning oxidation numbers to organic compounds The oxidation state of any chemically bonded carbon may be assigned by adding -1 for each more electropositive atom (H, Na, Ca, B) and +1 for each more electronegative atom (O, Cl, N, P), and 0 for each carbon atom bonded directly to the carbon of interest. An atom is provided an oxidation state when it gains or loses certain electrons. Since the molecule consists of two nitrogen atoms, each of which must have the same oxidation state, then each nitrogen atom also has an oxidation number of zero.
