Nitrogen Properties

Nitrogen

Description

 

Nitrogen is a inert diatomic gas at standard conditions. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates, and cyanides, contain nitrogen. It occurs in all living organisms, and the nitrogen cycle describes movement of the element from air into the biosphere and organic compounds, then back into the atmosphere. It is a constituent element of amino acids and thus of proteins and nucleic acids. It resides in the chemical structure of almost all neurotransmitters, and is a defining component of alkaloids, biological molecules produced by many organisms.
