Nitrogen essays

Nitrogen essays Nitrogen is nonmetallic, odorless, colorless, and tasteless gas. Nitrogen makes up about 78% of the earths atmosphere. Rutherford discover nitrogen in 1772. On the periodic table of elements Nitrogen is diatomic and has the chemical symbol of N. The atomic number is 7, and its atomic weight is 14. There are 7 protons, neutrons, and electrons in a nitrogen atom. The gas can be condensed in liquid state that has a boiling point of -195.8 degrees celcius or froze at -209.9 degrees celcius. Even though nitrogen does not combine easily with other elements, the atoms are parts of many chemical There are many uses of nitrogen. Manufacturers can obtain pure nitrogen by making liquid air. After that they separate the nitrogen from the oxygen and other gases in air by distillation. After distilled nitrogen is collected under pressure in specially designed metal containers. The most important use of nitrogen is in the production of ammonia (NH3). Ammonia is used as a fertilizer, as a refridgerant, and in the production of nitric acid and other chemicals. Nitrogen compounds are also important to the making of drugs, dyes, explosives, poisons, and synthetic fibers. Nitrogen is one of the most important elements on the periodic table. All organisms must have nitrogen to live. Proteins are formed of amino acids, which nitrogen is part of all the amino acids. Nitrogen is always being removed from the air and teturned to it in a series of chemical reactions known as the nitrogen cycle. The nitrogen cycly is the circulation of nitrogen among the atmosphere, the soil and water, and the plants and animals of the earth. People influence the nitrogen cycle, but it is harmful to the atmosphere. The use of nitrogen fertilizers adds nitrogen to the soil, and then rain water carries unused fertilizer and other nitrogen compounds into streams and lakes, where the ...
