The main gases in clean air are nitrogen (N2), oxygen (O2), and argon (Ar). These gases make up the majority of Earth's atmosphere, with smaller amounts of other gases such as carbon dioxide (CO2) and trace amounts of other gases.
Nitrogen and oxygen are two of the primary gases that make up air. The third is argon.
there are many gases polluting the Earth but the main 2 are oxygen and carbon dioxide.
nitrogen & oxygen
The main three gasses are Nitrogen, Oxygen and Argon.
The main gases that make up the air we breathe are nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include argon, carbon dioxide, and trace gases such as neon and helium.
Oxygen, Nitrogen and Argon comprise 99% of the air.

The main gases present in air are nitrogen (about 78%), oxygen (about 21%), argon (about 0.9%), and carbon dioxide (about 0.04%). There are also trace amounts of other gases such as neon, helium, methane, krypton, and hydrogen.
just about every kind of gas but the main is nitrogen then oxygen if you look on the peroidic table of elements there will be a group called the noble gases those are the gases in the air
