Nitrogen finds application in the metals industry in welding, soldering, and brazing, where it helps prevent oxidation, carburization, and decarburization.
How is nitrogen made?
Commercial production of nitrogen is largely by fractional distillation of liquefied air. 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. Nitrogen can also be produced on a large scale by burning carbon or hydrocarbons in air and separating the resulting carbon dioxide and water from the residual nitrogen. On a small scale, pure nitrogen is made by heating barium azide, Ba (N 3) 2. Various laboratory reactions that yield nitrogen include heating ammonium nitrite (NH 4 NO 2) solutions, oxidation of ammonia by bromine water, and oxidation of ammonia by hot cupric oxide.

What is the name of the gas in the atmosphere?
About four-fifths of Earth’s atmosphere is nitrogen, which was isolated and recognized as a specific substance during early investigations of the air. 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 “fire air” was, of course, oxygen and the “foul air” nitrogen. 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. Later work showed the new gas to be a constituent of nitre, a common name for potassium nitrate (KNO 3 ), and, accordingly, it was named nitrogen by the French chemist Jean-Antoine-Claude Chaptal in 1790. 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 inability of nitrogen to support life (Greek: zoe) led Lavoisier to name it azote, still the French equivalent of nitrogen.

What is nitrogen in plants?
Nitrogen (N) is an essential element of life and a part of all plant and animal proteins. Nitrogen can be produced in several ways. Some plants, such as soybeans and other legumes, recover nitrogen directly from the atmosphere or from the soil in a process know as "fixation," whereby the plant converts nitrogen into carbohydrates, essential amino acids, and proteins. Nitrogen is commercially recovered from the air as ammonia, which is produced by combining nitrogen in the atmosphere with hydrogen from natural gas. Ammonia is converted to other nitrogen compounds, the most important of which are urea (NH2CONH2), nitric acid (HNO3), ammonium nitrate (NH4NO3), and ammonium sulfate [ (NH4)2SO4]. With the exception of nitric acid, these compounds are widely used as fertilizer.

How to extract nitrogen from blood?
The method used a newly developed apparatus for extracting nitrogen or other inert gases from blood by flushing the specimen with another gas. The apparatus consisted of a gas tight syringe modified to incorporate a stainless steel tube with a fine bore lumen which traverses the plunger, creating a gas inlet. To investigate the utility of the new methodology, the apparatus was used in conjunction with a mass spectrometer to measure the blood nitrogen content of healthy normobaric, nonsmoking, adult volunteers. Eleven subjects were studied in the first tests and then blood was obtained from seven of the subjects for repeat analysis several weeks after the first measurements. The mean blood nitrogen was found to be 11.7 microliter/milliliter, in close agreement with values cited in the literature. The variation within subjects for repeat samples was significantly less, p-value less than 0.003, than the variation between different subjects. This suggests there may be true differences in nitrogen content between different individuals. The authors conclude that the new apparatus and methods have a potentially valuable role in future decompression research.

What is the most important element for plants?
Nitrogen is a critical limiting element for plant growth and production. It is a major component of chlorophyll, the most important pigment needed for photosynthesis, as well as amino acids, the key building blocks of proteins. It is also found in other important biomolecules, such as ATP and nucleic acids. Even though it is one of the most abundant elements (predominately in the form of nitrogen gas (N2) in the Earth's atmosphere), plants can only utilize reduced forms of this element. Plants acquire these forms of "combined" nitrogen by: 1) the addition of ammonia and/or nitrate fertilizer (from the Haber-Bosch process) or manure to soil, 2) the release of these compounds during organic matter decomposition, 3) the conversion of atmospheric nitrogen into the compounds by natural processes, such as lightning, and 4) biological nitrogen fixation. Biological nitrogen fixation (BNF), discovered by Beijerinck in 1901, is carried out by a specialized group of prokaryotes. These organisms utilize the enzyme nitrogenase to catalyze the conversion of atmospheric nitrogen (N2) to ammonia (NH3). Plants can readily assimilate NH3 to produce the aforementioned nitrogenous biomolecules. These prokaryotes include aquatic organisms, such as cyanobacteria, free-living soil bacteria, such as Azotobacter, bacteria that form associative relationships with plants, such as Azospirillum, and most importantly, bacteria, such as Rhizobium and Bradyrhizobium, that form symbioses with legumes and other plants.
