The gases in air are mainly oxygen, nitrogen, a small amount of carbon dioxide, and many other gases. In fact, oxygen and nitrogen together constitute 99% of air, while the remaining 1% is constituted by carbon dioxide and a few other gases and water vapour.

However, the composition of air (the quantity of various elements present in air) may vary from place to place.
