What happens when nitrogen fills its valence shell?

The choices can be found elsewhere and as follows:

A.Three electrons are lost, Creating N+3
B. Three electrons are lost, Creating N-3
C.Three electrons are gained, Creating N+3
D.Three electrons are gained, Creating N-3

I think the correct answer is option D. When nitrogen fills its valence shell then three electrons are gained, Creating N-3. Hope this answers the question.

We can use solar powered cars or ride bikes instead of cars that burn fossil fuels
