Nitrogen's atomic number is 7 and its symbol is N. Nitrogen makes up about 78% of the atmosphere on earth. It is an important element in all organisms, primarily in amino acids. Nitrogen plays a major role in the manufacture of ammonia, nitric acid, propellants, explosives, fertilizers, and thousands of other commercial goods. Another industry that widely uses nitrogen is the medical field. Nitrogen forms the base of many pharmaceuticals including nitrous oxide (laughing gas). 

This sample for nitrogen is sealed in a glass ampule under a vacuum. This means that it is capable of glowing in an electric field. When the sample is electrically excited it produces a faint reddish purple light.
