A diatomic molecule must be linear, but it is the disposition of the electrons that is important.

Explanation:

Each nitrogen atom (Z=7) has 5 valence electrons, giving 10 valence electrons in total. 4 of these electrons are presumed to form lone pairs on each nitrogen atoms; the remaining 6 electrons are shared between the nitrogen nuclei to form a very stable triple bond, :N-=N:. This triple bond accounts for the very short N-N distance (1.10xx10^(-10)m), and the high bond dissociation energy of 226 kcal*mol^-1.
