Here's why:

* Electronic Configuration: The electronic configuration of nitrogen is 1s² 2s² 2p³.

* 2p Sublevel: The 2p sublevel has three orbitals (2px, 2py, and 2pz), each capable of holding a maximum of two electrons.

* Nitrogen's 2p Electrons: Nitrogen fills these orbitals with three electrons, one in each orbital.
