Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere. Argon 0.9% (inert gas) is there in the atmosphere.
What is the percentage of inert gases in the air?
What percentage of gases are in the air?
What's in the Air? By volume, the dry air in Earth's atmosphere is about 78.09 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon. A brew of trace gases accounts for the other 0.03 percent, including the greenhouse gases carbon dioxide, methane, nitrous oxide and ozone.
Does air contain inert gases?
All the noble gases are present in Earth's atmosphere and, except for helium and radon, their major commercial source is the air, from which they are obtained by liquefaction and fractional distillation.
Which gas has highest percentage in air?
Nitrogen Gases. The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at .
What is the highest percentage of oxygen we can breathe?
60% O2 (upper limit for indefinite human survival), rest a mix of Nitrogen and other gases with a biome similar to earth.
How many inert gases are there?
The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
What is inert 9th gas?
There are some elements which do not combine with other elements. These elements are : Helium,Neon, Argon, Krypton, Xenon and Radon. They are known as noble gases or inert gases because they do not react with other elements to form compounds.
Which gas has lowest percentage in air?

| *Water | H2O | 0 to 4% |
| Argon | Ar | 0.93% |
What percentage of air is oxygen?
21 percent The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
