nitrogen (Noun)
A chemical element symbol N with an atomic number of 7 and atomic weight of 14. 0067.
nitrogen (Noun)
Molecular nitrogen N2, a colorless, odorless gas at room temperature.
nitrogen (Noun)
A specific nitrogen within a chemical formula, or a specific isotope of nitrogen.

nitrogen (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.

nitrogen
Gaseous, non-metallic chemical element with symbol N and atomic number 7.

nitrogen
nī′tro-jen, n. a gas forming nearly four-fifths of common air, a necessary constituent of every organised body, so called from its being an essential constituent of nitre.—adjs. Nitrogen′ic, Nitrog′enous.—v.t. Nitrog′enise, to impregnate with nitrogen.—n. Nitrom′eter, an apparatus for estimating nitrogen in some of its combinations. [Gr. nitron, and gennaein, to generate.]

Nitrogen is a nonmetal chemical element. It has the chemical symbol N and atomic number 7. Its stable nuclei typically contains 14 nucleons (7 protons and 7 neutrons). It has 5 electrons in its outermost shell.

Air is made up of about 78% nitrogen and about 22% oxygen.

Nitrogen is not poisonous. We can safely breathe it when it is a part of air, but we cannot breathe pure nitrogen by itself, because it does not have the oxygen that we need to live.

Nitrogen is formally considered to have been discovered by Daniel Rutherford in 1772, who called it "noxious gas" or "fixed gas".

Nitrogen Oxide is a typical medical use for nitrogen, also known as "laughing gas" it gives the effect of feeling "high", or "pain-free".
