Solution
The correct option is A Nitrogen will share 3 electrons to form a diatomic molecule.
Nitrogen has 5 electrons in its outermost orbit. Thus, it will share 3 electrons with another nitrogen atom out of the 5 outermost electrons to attain octet configuration. Thus, both nitrogen atom will share 3 electrons with each other, so total electrons shared are 6.
Since thus total count of electrons in the outermost orbit = 6 (Shared electrons) + 2 (Unshared electrons)
Thus nitrogen attains octet configuration, on sharing 3 electrons.
Since one bond is formed by 2 shared electrons, 6 shared electrons form 3 bonds.
Thus, the only option which is correct is A.
