Nitrogen Also nitrogen
Nitrogen is an enormously important element with a versatile chemistry. It is part of every protein. Our air consists to 78% of N2. The chemical bond between the two atoms in the nitrogen molecule is the strongest bond between two atoms of the same element. This makes N2 a very stable and inert gas. Ammonia, NH3, which itself is toxic, is the most important base material for the nitrogen chemistry and is one of the most produced chemicals in the world. From this, for example fertilizers and explosives are made.
