what is nitrogen

Nitrogen is an odorless, tasteless, colorless nonmetallic chemical element which appears in great abundance in the Earth's atmosphere. It also appears in a number of other compounds, and is a vital component of life on Earth for many organisms. In addition to inhaling nitrogen with every breath, most organisms also consume it in their food on a daily basis. Many different forms are commercially available, from the supercoolant liquid nitrogen to nitrous oxide, a type of anesthetic.
