It is nitrogen, followed by oxygen.
Nitrogen.
Nitrogen
The air (on ground level, not in a traffic jam!) is composed of ~80% N2, ~20% O2, 0-6% H2O (vary a lot), 0.03% CO2, 1% argon and then traces of other elements. The most abundant element is thus nitrogen N.
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
nitrogen (N)
Hydrogen, Nitrogen, Oxygen
Nitrogen is more abundant; our atmosphere is 78% Nitrogen.

The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
Nitrogen (N2) is the most abundant gas in the Earth's atmosphere having percent volume of 78.8 compare to Oxygen 20.95 %, which falls on the second place after Nitrogen.
In the atmosphere, Nitrogen is about four times as common as is Oxygen.
Carbon, Hydrogen, Nitrogen, Oxygen
Oxygen is the most abundant element in the human body, followed by Carbon, Hydrogen and Nitrogen. Calcium is abundant, as well.
carbon, oxygen, hydrogen and nitrogen - have in common
These elements are carbon, oxygen, hydrogen for the human body.For the earth crust oxygen, silicon, aluminium, iron.For oceans is water, composed from hydrogen and oxygen.For the atmosphere the important gases are nitrogen, oxygen and argon.
