Air is a well defined composition of various gases present in different proportions however, the principal components of air are:
1. Nitrogen 78 %
2. Oxygen
3. Carbon dioxide
4. Argon
5. Water vapours
6. Neon
7. Xenon
8. Krypton
9. Radon
10. Helium
Nitrogen and oxygen are two of the primary gases that make up air. The third is argon.
Oxygen, carbon dioxide (no air is perfectly pure oxygen),and trace gases. So the atmosphere is made up of many many gases
water vapor is different from other gases that make up air because it condenses out of air that has cooled
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.

Nitrogen and Helium
I wouldn't say that many chemicals occur naturally in the air, however Oxygen and Nitrogen are the two main gases that make up the Earth's atmosphere.
Oxygen and nitrogen.

The active gas in the air is HYDROGEN
Hydrogen and Helium
1. Nitrogen - cca. 78 % 2. Oxygen - cca. 21 % 3. Argon - cca. 1 %
