By far, the most abundant gas in the Earth's atmosphere is nitrogen, which accounts for about 78% of the mass of dry air. Oxygen is the next most abundant gas, present at levels of 20 to 21%. Although humid air seems like it contains a lot of water, the maximum amount of water vapor that air can hold is only about 4%.

The atmospheric gases include nitrogen, oxygen, carbon dioxide, water vapor, argon, and trace gases. Among the trace gases which are present in only small amounts, are neon, helium, krypton, and xenon. Nitrogen is the most abundant gas in the atmosphere. Nitrogen makes up 78 % of the Earth's atmosphere.
