Nitrogen is essential to life on Earth. It is a component of all proteins and it can be found in all living systems. Nitrogen compounds are present in organic materials, foods, fertilizers, explosives and poisons. Nitrogen is crucial to life, but in excess it can also be harmful to the environment.
Nitrogen is an element that can combine with itself or with other elements to make different compounds. For instance nitrogen gas, N 2, is a compound made when two nitrogen atoms form a chemical bond. It makes up about 80% of the atmosphere, while oxygen gas, O 2, makes up a little less than 20% of the atmosphere.itrogen is an element that can combine with itself or with other elements to make different compounds.
