__ **History** __
 * Nitrogen was discovered by Daniel Rutherford in Scotland. It was discovered in 1772 and also in the 18th century. Daniel put a mouse in a bell jar and let it suffocate with nitrogen so it took a little while. Then he put another mouse in without nitrogen and it died sooner. Nitrogen is a noble gas and it is used for many things! It is used for car, It is 78.1% of the air, It is in your body, it is almost practically in everything on this living planet. But the cool thing is you can’t see it! **

** __Intresting Facts__ Nitrogen is used in rocket fuels. You breathe the nitrogen in the air. Air is mostly nitrogen. It is also odorless and tasteless. Also nitrogen is colorless. It is a gas it also makes up 78%of the air. It is found in food so your body is 3% nitrogen weight so nitrogen is pretty important in the world. The cost varies from for the least amount which is 25 cents for the smallest amount of nitrogen you can get. ** __

**Daniel Rutherford (November 3, 1749 – November 15, 1819), was born in Edinburgh, Scotland. He went to University of Edinburgh where his father, John Rutherford, was a professor of medicine. He was also a maternal uncle of the famous poet Walter Scott.** One area for use is to preserve freshening of foods by packaging them in nitrogen. This helps food not spoil, so it doesn’t suffer from other chemicals. For years, argon gas had been used in incandescent light bulbs to prevent the tungsten filament from burning up, since argon is an inert material. Nitrogen is now more expensive because of argon. Other areas where nitrogen is used is in dealing with liquid explosives as a safety measure, in military aircraft fuel systems to reduce the fire hazard, and in the production of electronic parts such as transistors, diodes and integrated circuits. **

** Nitrogen is a component of many organic molecules. It forms an essential part of amino acids and DNA. Nitrogen is essential for all living cells. What is the nitrogen cycle? Nitrogen is the major component of earth's atmosphere. It enters the food chain by means of nitrogen-fixing bacteria and algae in the soil. This nitrogen has been 'fixed' is now available for plants to absorb. These types of bacteria form a symbiotic relationship with legumes--these types of plants are very useful because the nitrogen fixation enriches the soil and acts as a 'natural' fertilizer. The nitrogen-fixing bacteria form nitrates out of the atmospheric nitrogen which can be taken up and dissolved in soil water by the roots of plants. Then, the nitrates are incorporated by the plants to form proteins, which can then be spread through the food chain. When organisms excrete wastes, nitrogen is let go into the environment. **
