Note that the sign of the oxidation states and the number of atoms associated with each oxidation state must be considered. Synthetic chemists customarily tune the redox characteristics of π-conjugated molecules by introducing electron-donating or electron-withdrawing substituents onto the molecular core, or by modifying the length of the π-conjugated pathway. The typically-used oxidation state of nitrogen in N 2 O is +1, which also obtains for both nitrogens by a molecular orbital approach. Nitrogen compounds, on the other hand, encompass oxidation states of nitrogen ranging from -3, as in ammonia and amines, to +5, as in nitric acid.

Because ammonia is neutral, the individual oxidation numbers must sum to zero. 5 years ago. Oh, I always advocate properly assigning formal charges to all atoms that need them, which is why I wouldn’t have upvoted your answer if only the first structure were shown ;). There are 2 different nitrogen atoms in $\ce{NH4NO3}$, one having oxidation number -3 and one with +5.They are different, having separate oxidation numbers independently of each other.
