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

Explanation:

Nitrogen, "N", is located in Group 15, Row 2 of the Periodic Table.

It has atomic number 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 noble gas shorthand notation, you will get from

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

to

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