Under standard conditions nitrogen is a colorless ,tasteless odorless gas. It forms diatomic molecules,Which means that are two nitrogen atoms per molecules in nitrogen gas (N2)  in this configuration nitrogen is very inert, meaning that it doesn't typically react with other compounds.

Nitrogen becomes a liquid at_210.00 degrees C Liquid nitrogen looks water.

Common compounds with nitrogen atoms includes ammonia (NH3), Nitrous oxide (N2O),nitrites, and nitrates. Nitrogen is also found in organic compounds such as amines, amides, and nitro groups.
