Here's why:
* Location on the Periodic Table: Nitrogen is located in Group 15 (also known as the pnictogens) of the periodic table. Most elements in this group are nonmetals.
* Physical Properties: Nonmetals generally have the following characteristics:
* They are poor conductors of heat and electricity.
* They tend to be brittle (easily broken) in their solid state.
* They have low melting and boiling points.
* They can be gases, liquids, or solids at room temperature.
* They often exist as diatomic molecules (like N2).
* Chemical Properties: Nonmetals tend to gain electrons when they form chemical bonds, becoming negatively charged ions (anions).
Nitrogen fits all of these criteria, confirming its classification as a nonmetal.
