The blood urea nitrogen (BUN) test measures the level of urea nitrogen in a sample of the patient's blood.
Air
Nitrogen monoxide is a diatomic gas at standard temperature and pressure.
N2
California standard test

kjehdahl method
Nitrogen oxides
The percentage of nitrogen in pure, dry ,standard air is 78,084 % (by volume).
No. Nitrogen is a nonmetal, which is a gas at standard temperature. Only metals rust or corrode.
Nitrogen is usually quite unreactive at both standard pressure and standard temperature. Nitrogen is relatively unreactive because nitrogen molecules are joined together by triple bonds, and these bonds are some of the strongest bonds that can exist between molecules.
Nitrogen ice is solid. Liquid nitrogen is liquid. At standard temperature and pressure, nitrogen is gaseous.
