Hydrogen, followed by oxygen. Argon is unreactive.
Argon, Neon, Chlorine, Methane, Oxygen, Hydrogen. There are plenty of others.
Hydrogen is the most chemically reactive among the elements listed. It readily reacts with other elements to form compounds, while helium, argon, and neon are inert gases and generally do not undergo chemical reactions under normal conditions.
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.
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
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!
Elementally, it reacts most commonly with hydrogen and oxygen. But in the forms of ammonia or nitrates, it will react with most elements.
Argon, Neon, Chlorine, Methane, Oxygen, Hydrogen. There are plenty of others.
The three most abundant gases in Earth's atmosphere are nitrogen (78%), oxygen (21%), and argon (0.93%).

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.
All gases - excepting noble gases- can react with sulfur; the most importants are the reactions with hydrogen and oxygen.
