Here's why:

* Location on the periodic table: Nitrogen is found in Group 15 (also known as the pnictogens), which primarily contains nonmetals.

* Properties: Nonmetals typically have the following characteristics:

* Poor conductors of heat and electricity

* Brittle (not malleable or ductile)

* Gases or solids at room temperature (nitrogen is a gas at room temperature)

* Chemical behavior: Nitrogen tends to form covalent bonds, a characteristic of nonmetals.
