What is the Lewis structure of N2?

In order to come up with this answer, you first need to know the number of valence electrons for Nitrogen. Since $N$ is a member of the Group 5A (based on the periodic table), the number of electrons in its outermost shell must be 5.
Here is the electron dot structure for a single $N$ atom:
The total number of valence electrons between the two $N$ atoms is $10 {e}^{-}$. Also, for the structure to be correct, it must follow the octet rule (eight electrons per atom). Hence,
