Question

What is the percentage of nitrogen in air?

Answer 1

Our atmosphere contains gases like phosphorus, oxygen, nitrogen, carbon, krypton, xenon, chlorine etc. The most abundant element in our atmosphere is the element Nitrogen.

Complete step by step answer:
We know that our Earth contains a lot of gases. The percentage of other gas including phosphorus, argon etc., is 1%, oxygen is 21%, nitrogen is 78% and carbon dioxide is 0.04% approximately in the atmosphere.
Therefore, the most abundant element in our atmosphere is the element Nitrogen and it is present in 78%.

Additional information:
The earth is mainly composed of 5 layers which are the exosphere, the thermosphere, the mesosphere, the stratosphere, and the troposphere.
The troposphere is very dense. The surface extends from 8 to 14.5 kilometers high which is approximately 5 to 9 miles. The stratosphere is placed above the troposphere and the surface of this layer extends to almost 50 kilometers high which is approximately 31 miles. Ozone is present on this surface. The mesosphere is placed above the stratosphere. The surface of the mesosphere extends to 85 kilometers high which is approximately 53 miles. The thermosphere is placed above the mesosphere. The surface of the thermosphere extends to almost 600 kilometers high which is approximately 372 miles. Just above the thermosphere lies the ionosphere. The surface of this layer extends from about 48 kilometers which is approximately 30 miles above the ionosphere surface and to the edge of space of about 965 kilometers which is approximately 600 miles. Above the ionosphere exosphere lies the exosphere. Exosphere is the topmost layer of the atmosphere. The surface of the exosphere extends to 10,000 kilometers high which is approximately 600 miles.

Note:
It is important to know that by the process of nitrogen fixation molecular nitrogen is converted into ammonia in the air. There exist two types of nitrogen fixation. These are biological nitrogen fixation and physical nitrogen fixation.
