Nitrogen exists in both natural forms of isotopes, and four hot isotopes thrust been artificially prepared. Nitrogen melts at -210.01° C (-346.02° F), boils at -195.79° C (-320.42° F), and has a assiduousness of 1.251 g/liter at 0° C (32° F). The nuclear weight of atomic number 7 is 14.007.
Nitrogen is obtained from the atm by acquittance air over het up(p) strapper or iron. The type O is removed from the air, leaving atomic number 7 compound with some squashy gases. Pure normality is obtained by incomplete evaporation of liquid air because liquid nitrogen has a lower boiling point than liquid oxygen, the nitrogen evaporates of...If you fate to get a full essay, order it on our website:
