The remaining 1% is made up of trace gases such as argon, carbon dioxide, neon, helium, methane, krypton, hydrogen, and xenon.

Nitrogen is an important component of the atmosphere and plays a vital role in sustaining life on Earth. It is an essential nutrient for plants and animals and is a key component of proteins, nucleic acids, and other biological molecules. Nitrogen is also used in the manufacturing of fertilizers, industrial chemicals, and other products.
