Element type: non-metallic element

Nitrogen is a colorless, odorless gas. The usual monomolecular form of nitrogen is nitrogen gas. It is colorless, tasteless and odorless, and is a chemically inert gas which is not easy to have chemical reactions, and it does not support combustion, slightly soluble in water and ethanol. It is used in the synthesis of ammonia, the production of nitric acid, as a substance protection agent, refrigerant.
