Answer:

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#
