Question

HOw many electrons does nitrogen gain in order to achieve a noble-gas electron configuration?

a. 4
b. 2
c. 1
d. 3

Answer 1

Nitrogen needs to gain 3 electrons to achieve a noble-gas electron configuration.

Step-by-step explanation:

Nitrogen needs to gain 3 electrons in order to achieve a noble-gas electron configuration. This is because nitrogen has 5 valence electrons and needs a total of 8 to achieve stability, like the noble gas neon (which is in the same group as nitrogen). By gaining 3 electrons, nitrogen will have a total of 8 electrons in its outermost shell, achieving the desired electron configuration.
