Earth's atmosphere is 78% nitrogen, 21% oxygen, and 0.934% argon. The remaining 0.066% (66/1000 of 1%) is made up of a combination of carbon dioxide, hydrogen, ozone, methane, carbon monoxide, helium, neon, krypton, and xenon etc.
Nitrogen is the main element in the Earth's atmosphere. Nitrogen makes up 78 percent of the atmosphere. Oxygen makes up 20 percent. Other elements in small amounts are argon, carbon dioxide, neon, and methane.
The earth's atmosphere is made up of:
-78% Nitrogen.
-21% Oxygen.
-0.93% Argon.
-0.038% Carbon Dioxide.
-And traces of other gases.
So the answer is.........Drumroll please.....
NITROGEN!!!

Water vapor (H2O)
~0.40% over full atmosphere, typically 1%-4% at surface
Nitrogen is the largest component of the atmosphere. It comprises about 78% of dry air.

There are 4 elements that compose all living things. Hydrogen, Oxygen, Carbon and Nitrogen. Out of them, the first 3 are the main ones.
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
The main elements of lpg are, butane , methane(CH4) and etyl mercaptan.
The helium atom does not form a diatomic molecule, unlike the main components of the atmosphere, nitrogen and oxygen, and it is a very light atom, actually the second lightest of all atoms (second only to hydrogen) and it is gravity which holds our atmosphere in place on the surface of the Earth, so the lighter the particle, the more easily it can escape into space.
Oxygen, carbon dioxide (no air is perfectly pure oxygen),and trace gases. So the atmosphere is made up of many many gases

Type Of Gas Most In The Earth Is Methane.
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
Green plants evolved adding oxygen to the atmosphere.
Nitrogen and Oxygen are the two main constituents of air.
Main group elements have elements from groups 1 and 2, except hydrogen and groups 13 to 18. Main group elements are elements in groups who's lightest elements are shown by helium, lithium, boron, beryllium, carbon, nitrogen, oxygen, and fluorine.
In a gas cycle elements move through the atmosphere. Main reservoirs are the atmosphere and the ocean.Gas Cycles:CarbonNitrogenOxygen

The four main layers of Earth's atmosphere are Toposphere, Stratosphere, Mesosphere, and Thermosphere. (The Thermosphere ends at 62 miles from earth's surface. or, where space starts.TroposphereExosphereIonosphereOzonosphere
