Nitrogen gas (N₂) is a colorless, odorless, and inert diatomic molecule that makes up about 78% of the Earth's atmosphere. It plays a crucial role in various biological and chemical processes, particularly in the nitrogen cycle, which includes essential processes such as nitrification and denitrification. These processes are vital for converting nitrogen into forms usable by living organisms and returning it to the atmosphere, maintaining ecological balance.
