Nitrogen is a chemical element with symbol N and atomic number 7. Elemental nitrogen is a colorless, odorless, tasteless, and mostly inert diatomic gas at standard conditions, constituting 78.09 percent of Earth’s atmosphere by volume.
Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air or by mechanical means using gaseous air. Commercial nitrogen is often a byproduct of air-processing for industrial concentration of oxygen.
Nitrogen gas has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable. Liquid nitrogen is also used to cryogenically freeze objects.
