Dry air  contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases.  Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.

Air is a mixture of gases. Air contains  Nitrogen(78%) and oxygen (21%). In fact, these two gases together make up the most of our atmosphere (78%+21%=99%). The remaining 1% contains carbon dioxide, argon and other gases. It also contains water vapour, smoke and dust particles.
