Answer:

The noble gas configuration of nitrogen is: #["He"]"2s"^2"2p"^3"#.

Explanation:

Nitrogen is atomic number 7 on the periodic table. This means that every nitrogen atom has seven protons in its nucleus. A neutral nitrogen atom also has seven electrons.

The noble gas electron configuration contains the symbol for the noble gas in the previous period and the rest of the configuration written out. Nitrogen is in the 2nd period of the periodic table, so the previous noble gas is helium.

The noble gas configuration of nitrogen is: #["He"]"2s"^2"2p"^3"#.
