Nitrogen.

History
(Latin: nitrum, Greece: nitron, natural soda, forming) Nitrogen was discovered by chemist and physicist Daniel Rutherford in 1772. He separates the oxygen and carbon dioxide from the air and shows the remaining gas does not support combustion or living organisms. At the same time there are some scientists who conduct research lainny of nitrogen. They are Scheele, Cavendish, Priestley, and others. They called this gas air without oxygen.

Source
Nitrogen gas (N2) contained as many as 78.1% in the air. In comparison, the atmosphere of Mars contains only 2.6% nitrogen. From the earth's atmosphere, nitrogen gas can be produced through the process of liquidation (Liquefaction) and fractional distillation. Nitrogen is found in living things as part of biological compounds.

Element
French chemist Antoine Laurent Lavoisier named nitrogen azote, meaning without life. However, nitrogen compounds found in food, fertilizers, poisons and explosives. As nitrogen gas bewarna no, no smell and is considered an inert element (elements that do not react). As a liquid, it is also not bewarna and scented and have the same ketampakan with water. Nitrogen gas can be prepared by heating a solution of ammonium nitrate (NH4NO3) in water.

Nitrogen compounds
Sodium nitrate (NaNO3) and potassium nitrate (KNO3) is formed by the decomposition of organic material with metal compounds such. In the dry conditions in beberapat place, saltpeters (salt) is found in sufficient quantities and used as fertilizer. Inorganic compounds other nitrogen is nitric acid (HNO3), ammonia (NH3) and oxides (NO, NO2, N2O4, N2O), cyanide (CN-), etc.. Nitrogen cycle is one of the important processes in nature for living organisms. Although nitrogen gas did not react, bacteria in the soil can improve the nitrogen into a useful form (as fertilizer) for plants. In other words, nature has provided a method to produce nitrogen for plant growth. Animals then eat these plants where nitrogen had been contained in their system as a protein. Cycle is complete when the bacteria, other bacteria convert the waste nitrogen compounds into nitrogen gas. As the main component of proteins, nitrogen is an essential ingredient for life.

Ammonia
Ammonia (NH3) is a commercial compound of nitrogen is most important. He produced using the Haber process. Natural gas (methane, CH4) reacts with steam to produce carbon dioxide and hydrogen gas (H2) in a two-step process. Hydrogen gas and nitrogen gas and then reacted in the Haber process to produce ammonia. Gas is not bewarna stinging smell can be easily liquidated. Even the liquid form of this compound is used as nitrogen fertilizer. Ammonia is also used to produce urea (NH2CONH2), which is also used as fertilizer in the plastics industry, and in the farming industry as a livestock food supplement. Ammonia is often the first compound to a lot of nitrogen compounds.
