Question

The total number of electrons in a nitrogen atom is 7. Find the number of valence electrons in it.

Answer 1

Explanation:

Atomic number of Nitrogen is 7.

The electronic configuration of Nitrogen atom: 2,5.

K-shell squires= 2electrons.

L-shell squires= 5 electrons.

L-shell is incomplete shell, so it is the outermost shell.

Valence electrons are the number of electrons in

the outermost shell.

The valence electrons in Nitrogen atom is 5 electrons.
