Question

Do `N` and `N` form a polar covalent bond?

Answer 1

No

Explanation:

No they form a non polar covalent bond. In this case the bond is between two nitrogen atoms. Now since its the same atom, neither can pull the electrons towards itself more than the other and hence they end up sharing the electrons equally. Equal sharing of electrons leads to both atoms having the same charge on them and hence it is non polar

Answer 2

Nope.

Explanation:

`N` and `N` can bond together to form nitrogen gas, `N_2`, which makes up around `78%` of the gas in the air. It is non-polar, because it is made up of two identical nitrogen atoms, both of which have the same electronegativity. Therefore none of the nitrogen atoms pull the electrons at a greater strength towards its nucleus than the other, and so the bond is not polar.
