# What is the electron configuration of nitrogen (N) ?

The of ##"N"## is ##"[He]"color(white)(l) 2s^2 2p^3##.

**Nitrogen**, ##"N"##, is located in Group 15, Row 2 of the .

It has ##7##.

This tells you that a **neutral** nitrogen atom has a total of ##7## electrons.

If you add electrons according to the **Aufbau Principle**, you get the electron configuration

##"N: " 1s^2color(white)(l) 2s^2 2p^3##

If you use the , you will get from

##"N: " overbrace(1s^2)^(["He"]) 2s^2 2p^3##

to

##"N: " ["He"]color(white)(l) 2s^2 2p^3##
