compromise? Hydrogen, if you could find enough to convert the oxygen into water.
If you mean comprise then its 79 % nitrogen, 21 & oxygen, and 1% argon
Nitrogen
Nitrogen is the most common element in the Earth's atmosphere.
Nitrogen is the most abundant element in the earth's atmosphere.
The most common element in the Earth's Crust is: Iron 33% Atmosphere: Oxygen 85% Ocean: Oxygen 65% Good Luck, Textbo7
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.
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
Hydrogen is the lightest and most abundant element in the universe, while nitrogen is a nonmetallic element that makes up about 78% of Earth's atmosphere. Hydrogen is a highly flammable gas, while nitrogen is non-reactive and commonly used in inert atmospheres.
Nitrogen and hydrogen
Ammonia is not a element. It is a compound (NH4) made up of the elements Nitrogen and Hydrogen.
The elements of hemoglobin are carbon, hydrogen, nitrogen, sulfur, iron, and oxygen. The chemical formula is C738H1166N812O203S2Fe
nitrogen
The main element in the atmosphere is Nitrogen. The second is Oxygen.
