Nitrogen is a Group 15 element, has an atomic mass of 14. It makes up about 78% of the atmosphere and it is the fifth most abundant element in the universe. The French chemist Antoine Laurent Lavoisier named nitrogen azote, meaning without life. However, its compounds are vital components of foods, fertilizers, and explosives. Nitrogen gas is colorless, odorless, and generally inert. As a liquid it is also colorless and odorless.
In 1772, Daniel Rutherford discovered Nitrogen. He had mixed oxygen and carbon dioxide, this two elements he removed them from air. Nitrogen is used in very large amounts for steel mill products and in drug industries. Nitrogen is used for freezing food and transporting it. Liquid nitrogen is used in missile work, as an insulator for space ships and by oil industries to make crude oil. But, the largest use of nitrogen is for the production of ammonia (NH3). Large amounts of nitrogen are combined with hydrogen to produce ammonia. Large amounts of ammonia are then used to create fertilizers, explosives and, nitric acid (HNO3).
Nitrogen has a melting point of 63.29K, a boiling point of 77.4K and a critical temperature of 126.2K. From a source in our atmosphere, nitrogen gas can be obtained by liquefaction and fractional distillation. Nitrogen is found in all living systems as part of the makeup of biological compounds. Our lives would be different without Nitrogen in that we wouldn't have many types of oil, fertilizers, and explosives. There is no substitute for Nitrogen; therefore, without it life would be very different.
NITROGEN A physician named Daniel Rutherford discovered nitrogen in Scotland in 1772. ... The atomic number of nitrogen is 7. ... Active nitrogen returns to its ordinary nitrogen form in about a minute. In conclusion, nitrogen is a very important element. ... Nitrogen also forms many important compounds. ...
Nitrogen has the unique properties of both carbon and phosphorus. The difference is plants and animals cannot absorb nitrogen in it pure state. ... The nitrogen then follows the classic energy-flow pattern from producers to herbivores to carnivores and finally to decomposers. The nitrogen waste is released as bacteria in the soil. ... In the case of nitrogen the development of nitrogen, based fertilizers have created a new produce instead of the natural nitrogen. ...
Animals get nitrogen through the consumption of plants. Plants get there nitrogen through a process in which certain organisms turn nitrogen into the 2 usable forms for a plant, ammonium and nitrate. Legumes have nitrogen-fixing bacteria in their root nodules. These nitrogen-fixing bacteria take nitrogen and convert it to a usable form for the legume. ... In aquatic ecosystems some cyanobacteria fix nitrogen. ...
Carbon, nitrogen and phosphorus all play a big role in our environment and how things prosper or not. ... Nitrogen (N) is an essential component to living organisms, fourth behind oxygen, carbon and hydrogen. ... The nitrogen cycle is a complex one. ... The standard measurement for analyzing the global nitrogen cycle is the teragram (Tg), which is equal to a million metric tons of nitrogen. ... Lawn fertilizer contains nitrogen and phosphorus for both the roots and green growth. ...
Nitrogen produces proteins that all living things require. ... About 78% of the atmosphere is nitrogen. ... All living things require nitrogen to make proteins. For nitrogen to be useful, the nitrogen must first be converted into a nitrate. ... In this case, the released nitrogen is returned to the atmosphere and the nitrogen cycle is complete. ...
The narcosis develops with an increasing nitrogen partial pressure. ... Nitrogen is one of the main components of air (78%). ... When a diver starts breathing air under pressure, more nitrogen will dissolve until a new, higher nitrogen level is established. At this level, the partial nitrogen pressure in the blood and tissue is the same as the partial nitrogen pressure in the air. ... However, when there is too much nitrogen surplus and the diver surfaces too quickly, nitrogen is forming small bubbles in the blood and in the tissue. ...
Carbon, nitrogen and phosphorus all play a big role in our environment and how things prosper or not. ... Nitrogen (N) is an essential component to living organisms, fourth behind oxygen, carbon and hydrogen. ... The nitrogen cycle is a complex one. ... The standard measurement for analyzing the global nitrogen cycle is the teragram (Tg), which is equal to a million metric tons of nitrogen. ... Lawn fertilizer contains nitrogen and phosphorus for both the roots and green growth. ...
