Nitrogen melts at -210.01° C (-346.02° F), boils at -195.79° C (-320.42° F), and has a density of 1.251 g/liter at 0° C (32° F). The atomic weight of nitrogen is 14.007.

Nitrogen is obtained from the aureole by passing air over heated bulls eye or iron. The oxygen is removed from the air, leaving nitrogen mixed with any(prenominal) inert gases.
