Nitrogen is number 7 on the periodic table giving it 7 protons and 7 electrons. The first pair aare in the first energy level. The next pair are in the second energy level at the s level. The next 3 are not paired. They are in the p level but not paired. Therefore nitrogen is looking for 3 electrons to be stable . Nitrogen has a -3 charge as an ion. In the diatomic state, N2, it is sharing 3 pairs of electrons with the other N.

The Atomic Nomber for Nitrogen is 7, and if we write it's atomic arrangment is : 1S2, 2S2, 2P3
and as we know the "P orbital" is filled with 6 electron, "3" electrons is needed to fill the p orbital. so nitrogen only can contribute lonepair of electrons in reactions.

same reason oxygen does.
