Question

What is the electron configuration for a nitride ion?

Answer 1

The nitride ion is `N^(-3)`

The original electron configuration for nitrogen is

`1s^2 2s^2 2p^3`

In order to fulfill the octet rule, the nitrogen atom would take on three additional electrons giving nitrogen a -3 charge.

`N^(-3)` `1s^2 2s^2 2p^6`

I hope this was helpful.
