nitrogen

n. colorless odorless gas, dominant element in the atmosphere, non-metallic element used in the production of fertilizers and explosives (Chemistry)

Nitrogen (IPA: ) is a chemical element which has the symbol N and atomic number 7. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.1 y volume of Earth's atmosphere. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds, such as ammonia, nitric acid, and cyanides, contain nitrogen.

n. nitrogen, colorless odorless gas; dominant element in the atmosphere; non-metallic element used in the production of fertilizers and explosives (Chemistry)

(n.)
A colorless nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva.
