Nitrogen

Nitrogen is the seventh element in the periodic table. Nitrogen naturally occurs as a colorless and odorless gas, generally considered to be inert. As a liquid, it is also colorless and odorless, and is similar in appearance to water.
Nitrogen makes up 78% of Earth's atmosphere by volume. The compounds made of nitrogen, combined with other elements, are so active as to be most important in foods, poisons, fertilizers, and explosives.
