Answer: "Three Electrons Are Gained"(N⁻³)
Nitrogen has an Incomplete Octet With an Electronic Configuration of
1S²2S²2P³
The P orbital takes a Maximum of 6 electrons.
When this shell is filled... The electronic Configuration of Neon is obtained.
1S²2S²2P⁶
This is also know as the Nitride Ion (N⁻³).
