On a small scale, pure nitrogen is made by heating barium azide, Ba(N3)2. It is part of the group of "other" nonmetal elements. Poisonous and corrosive gas cylinders have yellow color while red colored cylinders indicate the inflammable gas in them. The inability of nitrogen to support life (Greek: zoe) led Lavoisier to name it azote, still the French equivalent of nitrogen. Carbon = Grey.

Nitrogen dioxide (NO₂) is a red, bad-smelling gas. This molecule is a colourless, odourless, and tasteless diamagnetic gas at standard conditions: it melts at −210 °C and boils at −196 °C. Oxygen. Nitrogen is a very light gas and is the lightest gas in its group (Group 15). The atmosphere of the Earth comprises of 78% nitrogen gas. in the diamond lattice during growth deep in the earth. The boiling temperature of nitrogen is −195.8 °C (−320.4 °F), about 13 °C (−23 °F) below that of oxygen, which is therefore left behind. At about the same time, nitrogen also was recognized by a Scottish botanist, Daniel Rutherford (who was the first to publish his findings), by the British chemist Henry Cavendish, and by the British clergyman and scientist Joseph Priestley, who, with Scheele, is given credit for the discovery of oxygen. Liquid nitrogen has also proven useful in cryogenic research. The Nitrogen is essential for plant growth. Nitrogen mustards can be clear, pale amber, or yellow colored when in liquid or solid form.

However, only the very rare type Ib diamonds maintain that original color. Nitrogen - The Element. Nitrogen constitutes on the average about 16 percent by weight of the complex organic compounds known as proteins, present in all living organisms. Nitrogen gas is colorless, odorless, and tasteless, which was discovered by a well-known scientist named Daniel Rutherford in 1772. Ionized-air glow is the fluorescent emission of characteristic blue–purple–violet light, often of a color called electric blue, by air subjected to an energy flux. Let us know if you have suggestions to improve this article (requires login). At higher temperatures it is a reddish-brown gas. Nitrogen is an odorless, tasteless, colorless nonmetallic chemical element which appears in great abundance in the Earth's atmosphere. Complex reasoning, decision-making ability, motor function, and manual dexerity decrease. Nitrogen gas has two molecules of Nitrogen therefore, the molecular formula of this gas is N2.

In the chemical industry, nitrogen is used as a preventive of oxidation or other deterioration of a product, as an inert diluent of a reactive gas, as a carrier to remove heat or chemicals and as an inhibitor of fire or explosions.
