The “fire air” was, of course, oxygen and the “foul air” nitrogen. Particle beam from a cyclotron. Nitrogen atoms have seven electrons and 7 protons with five electrons in the outer shell. Nitrogen first was considered a chemical element by Antoine-Laurent Lavoisier, whose explanation of the role of oxygen in combustion eventually overthrew the phlogiston theory, an erroneous view of combustion that became popular in the early 18th century. The atmosphere of Earth consists of 75.51 percent by weight (or 78.09 percent by volume) of nitrogen; this is the principal source of nitrogen for commerce and industry. Nitrogen dioxide is a chemical compound with the formula NO 2. Another material rich in nitrogen is guano, found in bat caves and in dry places frequented by birds. Nitrogen is a colorless, odorless, tasteless, diatomic and generally inert gas at standard temperature and pressure. Nitrogen finds application in the metals industry in welding, soldering, and brazing, where it helps prevent oxidation, carburization, and decarburization. Nitrogen. Carl Wilhelm Scheele, a Swedish chemist, showed in 1772 that air is a mixture of two gases, one of which he called “fire air,” because it supported combustion, and the other “foul air,” because it was left after the “fire air” had been used up. The atmosphere of the Earth comprises of 78% nitrogen gas. Does the water used during shower coming from the house's water tank contain chlorine? A major component of proteins is Nitrogen. 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. When they get normal again, they release light. Nitrogen plays an important role in the life of plants and animals on Earth through the nitrogen cycle. Among the elements, nitrogen ranks sixth in cosmic abundance. In the liquid state, nitrogen has valuable cryogenic applications; except for the gases hydrogen, methane, carbon monoxide, fluorine, and oxygen, practically all chemical substances have negligible vapour pressures at the boiling point of nitrogen and exist, therefore, as crystalline solids at that temperature. 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. However, only the very rare type Ib diamonds maintain that original color. The alpha phase is another allotropic form of nitrogen that it acquires by arranging in a cubic crystal when exposed to temperature lower than -237C. Liquid nitrogen has also proven useful in cryogenic research. 9 (2) Comments Dinara Ananda.
