why is there nitrogen in air?
Answers
Answer:
1. nitrogen is volatile in most of its forms
2. it is unreactive with materials that make up the solid earth
3. it is very stable in the presence of solar radiation.
The nitrogen molecule is heavier than most other molecules in the atmosphere, so it tends to settle towards the bottom. Other lighter gases, like hydrogen or helium, would tend to the top of the atmosplere, where it is more likely to be lost to space. So the heavier gases like nitrogen and oxygen tend to stick around, since they are at the bottom of the atmosphere.
Scientists believe that most of the nitrogen in the air was carried out from deep inside the earth by volcanoes.

Hey
Explanation:
Naturally, there is an ecological balance on Earth if people do not negatively affect this balance too much by burning fossil fuels that generate, among other gases, nitrogen oxides which under the action of radiation produce free radicals and disturb this balance. Nitrogen is predominant because among the basic chemical elements (C, H, O, N, S) nitrogen is the least reactive, it can not be stable in solid form to be incorporated in significant amounts into the soil structures (such as oxygen in the form of silicates or carbon in the form of carbonates). Instead, nitrogen is mobilized and maintained in this natural equilibrium by plants and by surface soil via various bacteria that convert it into ammonium, nitrites and nitrates, then being released back into the atmosphere as free nitrogen...
