What happens when nitrogen fills its valence shell?
a.three electrons are lost, creating n 3
b. three electrons are lost, creating n-3
c.three electrons are gained, creatingn 3
d.three electrons are gained, creatingn-3
The right answer is D. three electrons are gained, creating N-3
Nitrogen has 5 electrons in it's valence shell and octet rule states that the valence shell must have 8 electrons. To satisfy that, Nitrogen gains 3 electrons that are negatively charged.Therefore, it gets a negative charge.
