Nitrogen is the seventhelement in theperiodic table. Nitrogen naturally occurs as acolorless andodorlessgas, generally considered to be inert. As aliquid, it is also colorless and odorless, and is similar in appearance towater.
Nitrogen makes up 78% ofEarth'satmosphere by volume. The compounds made of nitrogen, combined with other elements, are so active as to be most important infoods,poisons,fertilizers, andexplosives.

Nitrogen occurs in many forms and compounds:
- Ammonia
- Brizeen nitrate
- Liquid nitrogen
- Nitrate
- Nitrogen oxide
- Nitrogen tetroxide
- Nitric acid
- Nitrogenated soil
- Nitrogenase compounds
- Potassium nitrate
- Rhodium nitrite
- Tri-nitrogen chloride
Liquid nitrogen was used for many visual effects onStar Trek; seeStar Trek: The Magazine Volume 1, Issue 9.
