Transcript of Nitogen

Name of element: Nitrogen
Chemical symbol: N
Group members: Olivia Keogh, Sierra Smith, and Aidan McCollough
Period/grade: 7/8
Date presenting: 5/6/10
•The atomic number for nitrogen is 7.
•The atomic mass is 14.0067.
•The classification of the element is a nonmetal.
•Nitrogen is in group 15 and the group is named after the element, nitrogen.
Historical info about the element...
Discovered by: Researchers are not exactly sure who discovered nitrogen, but they believe that it was either discovered by Scottish chemist and physician, Daniel Rutherford, English chemist Henry Cavendish, or Joseph Pristley, or Carl Wilhelm Scheete.
Time period(date) discovered: 1700’s
How the element was discovered: It was discovered when Daniel Rutherford, and other scientists who performed this experiment, removed oxygen and carbon dioxide from the air, and they noticed some kind of other gas lingered in the air.
Substances or items that contained this element during the time period: The substances nitrogen was in during that time were the air and every organism's protein cells, but that was not known at the time.
Historical uses for this element: People, other than scientists, used the element to breath and survive. Scientists were constantly experimenting with nitrogen to find what other uses there would be for this element.
Physical properties....
•It is colorless, odorless, and tasteless.
•The boiling point is -195.8 degrees Celsius.
•The melting point is -210 degrees Celsius.
•When nitrogen freezes it becomes a white solid that looks like snow.
•It is slightly lighter than air.

Chemical Properties...
•It is non-flammable.
•At high temperatures it will combine with certain active metals.
•At room temperature it is inactive.
•When nitrogen combines with oxygen it results in a lightning strike.
•Changing nitrogen as an element compound is called nitrogen fixation.

•Nitrogen, when mixed with hydrogen, makes ammonia; this process is called nitrogen fixation. This is a very difficult process.
•Then the ammonia can be combined with nitric acid to make ammonium nitrate, and then that can be mixed with sulfuric acid to make ammonium sulfate.
•Then ammonia can be mixed with oxygen to make nucleic acids.
•Pure nitrogen can also be used to make nucleic acids.

Modern uses and items containing this element...
•The element is used in light bulbs because nitrogen rarely reacts with other elements, even at extremely high temperatures.
It is used in tires.
•It also is able to protect historical documents, such as the Declaration of Independence, which is kept in a container filled with nitrogen gas.
•Liquid nitrogen can be bought and used to freeze foods, like in most grocery stores.
•Ammonia can be used by farmers to make synthetic fertilizers when they have large crops.
•Ammonia is also in many cleaning supplies.
•Nitric acid is in explosives, dyes, some synthetic rubbers and plastics, and as well as in the preparations of metals.
•Nucleic acids stores genetic information of an organism.
Interesting facts...

•On April 19, 1995 in Oklahoma City, a bomb exploded at the Alfred P. Murrah Federal Building. It killed 168 people and hundreds were injured. When investigating, investigators found that the bomb setters had purchased 2,000 pound of ammonium nitrate, a nitrogen compound used as an explosive.

•You would not be able to survive without nitrogen because firstly, it’s in the air. Secondly, it makes nucleic acids, which hold genetic information; this information tells every cell what to do in each organism.
