The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%).
The approximate mole fraction of nitrogen in the atmosphere is about 0.7808, and the approximate mole fraction of oxygen is about 0.2095. When combined, the mole fraction of nitrogen and oxygen in the atmosphere is approximately 0.9903.
Oxygen
Oxygen is the gas that makes up about 21 percent of the Earth's atmosphere.
The mole fraction of oxygen gas in air is approximately 0.21. This means that out of every 1 mole of air, 0.21 moles are oxygen gas molecules.

Oxygen is the second most abundant gas in Earth's atmosphere, making up about 21% of the air we breathe.
There is oxygen in the atmosphere of Saturn, but it is only a tiny fraction of the deep atmosphere, which is mostly hydrogen. It is not in a usable form as is oxygen on Earth.
The second most abundant gas in the Earth's atmosphere is oxygen, which makes up about 21% of the gases in the atmosphere.
This gas is oxygen.
Oxygen is not considered a greenhouse gas in the Earth's atmosphere.
