Nitrogen, oxygen, and argon make up practically all of the air (99.96%). Carbon dioxide and neon are both trace gaces: CO2 about 400 parts per million and neon about 18 parts per million by volume.
Water vapor suspended in the air can amount for up to 5% of its volume (in the most humid climates).
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
Nitrogen and oxygen make up 99% of Earth's atmosphere.

Nitrogen and Oxygen.
Earth's atmosphere makes up a blanket or an envelope around it, which is a mixture of many gases.
78% nitrogen, 21% oxygen, 1% carbon dioxide and other minute gases
Nitrogen and Oxygen make up nearly 99% of the dry atmosphere.
The two main gases that make up the atmosphere of Uranus are hydrogen and helium. The atmosphere also contains ammonia and methane.
The most prominent gases are nitrogen (78 percent), oxygen (21 percent) and argon (nine-tenths of a percent).
