Hydrogen, followed by oxygen. Argon is unreactive.
Fluorine even combines with argon, krypton, xenon, and radon. Even in dark, cool conditions, fluorine reacts explosively with hydrogen. http://en.wikipedia.org/wiki/Fluorine Fluorine even combines with argon, krypton, xenon, and radon. Even in dark, cool conditions, fluorine reacts explosively with hydrogen. http://en.wikipedia.org/wiki/Fluorine
Among the main four gases of the atmosphere (nitrogen, oxygen, argon, and carbon dioxide), oxygen is the most reactive. It readily reacts with other substances, making it essential for respiration and combustion. Nitrogen is relatively unreactive, while argon and carbon dioxide have even lower reactivity.
hydrogen or heliumhydrogen or helium
The most abundant example of a gas gas mixture is the air we breathe! It is a mixture of nitrogen, oxygen, water, argon, carbon dioxide and many trace gases!
Oxygen and Hydrogen
Elementally, it reacts most commonly with hydrogen and oxygen. But in the forms of ammonia or nitrates, it will react with most elements.

Humans need oxygen to live. Oxygen supports burning. It reacts with hydrogen to form water. It reacts with acids and bases to form oxides. It is one of the most abundant and important element on earth.
Hydrogen and hydrogen+fluorine.
The most common elements in space are Nitrogen and Oxygen. There is also Hydrogen and Argon. Surprisingly, there is more Nitrogen in space than Oxygen.
All gases - excepting noble gases- can react with sulfur; the most importants are the reactions with hydrogen and oxygen.

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.
Oxygen, hydrogen & Argon.In order, large percentages of Nitrogen, Oxygen followed by trace amounts of Argon are the most abundant elements in the earth's atmosphere.
