nitrogen
It is a solution of several gasses, the most abundant of which are nitrogen and oxygen.
As the third most abundant element, oxygen in the air is made by plants and algae.
hydrogen
Argon, Carbon Dioxide, Oxygen, and Nitrogen
Nitrogen and oxygen are the two most abundant gases in the air. They are actually elements and not compounds. The two most abundant compounds would be water vapor and carbon dioxide.

nitrogen and oxygen
Water is the usually the most abundant compound in the air, though the amount varies. It can be up to 4%. Next is carbon dioxide at 0.04%.
No, nitrogen is the most abundant gas in atmosphere.
It is a solution of several gasses, the most abundant of which are nitrogen and oxygen.
A Compound
The most abundant naturally occurring gas is nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas argon (Ar) is the third most abundant gas at 0.93%.
Air (clean or dirty) is a mixture, as it contains several different gases.
Nitrogen
Nitrogen, you can't survive on it obviously but you breath it in every day it is the most abundant gas in the atmosphere followed by oxygen I think.
78% of the air that we breathe is nitrogen gas.
