Nearly all of the Earth's atmosphere is made up of only five gases: nitrogen, oxygen, water vapor, argon, and carbon dioxide. Several other compounds also are present. Although this CRC table does not list water vapor, air can contain as much as 5% water vapor, more commonly ranging from 1-3%.
The answer is around twenty percent. Itâs true: even though we sometimes assume that all air is oxygen, only about a fifth of the atoms that make up our atmosphere are oxygen. The rest is things like nitrogen, carbon dioxide and hydrogen. Nevertheless, thatâs enough oxygen to breathe comfortably, so you can relax.
