Gosh, three? There are two primary constituents of the earth's atmosphere. Nitrogen makes up about 78% of it, and oxygen makes up about 21% of it. In the event you don't have your calculator, that's about 99% of the atmosphere. The other gases present and their quantities are: argon - 0.934%, carbon dioxide - 0.038%, water vapor - about 1%, and all the others make up about 0.002%. The latter half of the information is mined from Wikipedia. A link is supplied to our friends there. Surf on over to review and gather more factiods.
Oxygen, Nitrogen and Carbon Dioxide

The three primary gases that make up the atmosphere of Uranus are hydrogen, helium, and methane. Hydrogen is the dominant gas, followed by helium, while methane makes up a smaller but significant portion of the atmosphere.
Carbon dioxide used to make up most of Earth's early atmosphere.
The main gases that make up Earth's atmosphere are nitrogen (about 78%), oxygen (about 21%), argon (about 0.93%), and trace amounts of carbon dioxide, methane, and other gases. Water vapor is also an important component of the atmosphere.
The main gases in clean air are nitrogen (N2), oxygen (O2), and argon (Ar). These gases make up the majority of Earth's atmosphere, with smaller amounts of other gases such as carbon dioxide (CO2) and trace amounts of other gases.
Nitrogen, Oxygen and Argon make up 99% of the atmosphere
Nitrogen and oxygen make up 99% of Earth's atmosphere.
Earth's atmosphere makes up a blanket or an envelope around it, which is a mixture of many gases.
Nitrogen and Oxygen.
Nitrogen and Oxygen make up nearly 99% of the dry atmosphere.
Nitrogen N2 78.08% Oxygen O2 20.95%
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
The most prominent gases are nitrogen (78 percent), oxygen (21 percent) and argon (nine-tenths of a percent).
Argon and trace gases like neon, helium, and methane make up less than 1 percent of Earth's atmosphere.
Earth's atmosphere makes up a blanket or an envelope around it, which is a mixture of many gases.
