Brief description |
| |
Nitrogen gas is colorless, odorless, and relatively inert. Liquid nitrogen is also colorless and odorless, and is similar in appearance to water. There are two allotropic forms of solid nitrogen, a and b, with a transition between the two forms at -237°C. Nitrogen's melting point is -209.86°C, boiling point is -195.8°C, density is 1.2506 g/l, specific gravity is 0.0808 (-195.8°C) for the liquid and 1.026 (-252°C) for the solid. Nitrogen has a valence of 3 or 5.

Uses of Nitrogen |
| |
Nitrogen compounds are found in foods, fertilizers, poisons, and explosives. Nitrogen gas is used as a blanketing medium during the production of electronic components. Nitrogen is also used in annealing stainless steels and other steel products. Liquid nitrogen is used as a refrigerant. Although nitrogen gas is fairly inert, soil bacteria can 'fix' nitrogen into a usable form, which plants and animals can then utilize. Nitrogen is a component of all proteins. Nitrogen is responsible for the orange-red, blue-green, blue-violet, and deep violet colors of the aurora.
