# What is the number of valence electrons in nitrogen?

Jul 31, 2016

Nitrogen has $5$ valence electrons.

#### Explanation:

The thing to remember about main-group elements is that the group number gives you the element's number of valence electrons.

In your case, nitrogen, $\text{N}$, is located in group $1 \textcolor{red}{5}$, which means that it has $\textcolor{red}{5}$ valence electrons.

As you know, nitrogen exists as diatomic molecules, ${\text{N}}_{2}$. Each nitrogen molecule consists of two atoms of nitrogen that are bonded by a triple covalent bond.

This is a direct consequence of the fact that each nitrogen atom has $5$ valence electrons. Each atom can thus complete its octet by sharing three electrons.

Another thing to mention here is the fact that nitrogen's $5$ valence electrons causes the atom to form $3 -$ anions. This is the case because adding $3$ electrons to nitrogen's valence shell will give it a complete octet.
