1) In order for nitrogen to make a stable electronic configuration, it would have to gain three electrons.
Nitrogen is atomic number 7. Hence, the electronic configuration would be:
1s2, 2s2, 2p3
The p orbital is partially filled with 3 unpaired electrons. In order to be stable, the 3 electrons in the p orbital have to be paired. Hence, only by gaining 3 electrons can nitrogen obtain a stable electronic configuration.
2) The quantity the determines how two atoms would bond is the difference in the number of valence electrons in the atoms.
For example, an atom that is lacking 2 electrons will readily form a bond with another atom that has two free electrons.
