Question

The total number of electrons that take part in forming bonds in $N_2$ is:

• A. 2
• B. 4
• C. 6
• D. 10

Answer 1

The correct option is C 6

Structure of $N_2$ is $N\equiv N.$

In $N_2$ there are 3 bonds between two nitrogen atoms and each bond is formed by 2 electrons.

So, 3 bonds make it $3\times 2=6$ electrons in total.
