About Nitrogen
Nitrogen is a colorless, odorless, and generally inert diatomic gas at standard conditions. It forms a strong triple bond in its N2 molecule, making it relatively unreactive. Nitrogen is an essential component of amino acids, proteins, and nucleic acids. The Haber-Bosch process revolutionized agriculture.
Gebruiks & Programme
Fertilizers (ammonia), explosives, food preservation, cryogenics (liquid nitrogen), and inflating aircraft tires.
Fun Fact
Liquid nitrogen is so cold (-196 degrees C) it can flash-freeze almost anything, and nitrogen makes up 78% of every breath you take.
