What is Earth's atmosphere made up of?
- Nitrogen (78.1%) While nitrogen is the most abundant gas in Earth’s atmosphere, it only makes up 0.005% of Earth’s crust in weight (David Darling). Nitrogen is incredibly stable and requires a lot of energy to change forms.
- Oxygen (20.9%) Earth has the conditions for life to flourish. Oxygen is essential to human life as our lungs respire oxygen and uses it in metabolism.
- Argon (0.93%) As an inert gas, argon doesn’t bond or do much in the atmosphere. This is why there’s no argon cycle. But we have nitrogen and carbon because of their ability to bond with other elements.
- Carbon Dioxide (0.04%) Carbon is the most important element for building molecules essential for living things. As you can see from the long-term carbon cycle, carbon takes up various forms such as carbon dioxide (CO2), methane (CH4), and glucose (C6H12O6).
The noble gases (historically the inert gases, sometimes referred to as aerogens [1]) are the members of group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) and, in some cases, oganesson (Og).

Key points. The atmosphere is a mixture of gases. The atmosphere is mostly nitrogen (approximately 80%) and oxygen (approximately 20%). The remaining gases are found in much smaller proportions,...

Helium was the first of the rare gases to be discovered. In fact, its discovery is unique among the elements since it is the only element to be first identified in another part of the solar system before being discovered on the Earth. In 1868, Pierre Janssen (1824–1907), a French astronomer, was observing a total solar eclipse from India. Janssen u...
The rare gases form group 18 of the periodic table of elements. This is the vertical column of elements on the extreme right of the periodic table. As with other groups of elements, the placement of all the rare gases in the same group reflects their similar properties. The rare gases are all colorless, odorless, and tasteless. They are also monato...
Most of the rare gases have been detected in small amounts in Earth minerals and in meteorites, but are found in greater abundance in Earth’s atmosphere. They are thought to have been released into the atmosphere long ago as by-products of the decay of radioactive elements in Earth’s crust. Of all the rare gases, argon is present in the greatest am...
The properties of each rare gas dictate its specific commercial applications. Because they are the most abundant, and therefore the least expensive to produce, helium and argon find the most commercial applications. Helium’s low density and inertness make it ideal for use in lighter-than-air craft, such as balloons and blimps. Although helium has n...

Generally, all noble gases except oganesson (helium, neon, argon, krypton, xenon, and radon), nitrogen, and carbon dioxide are considered inert gases. The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [1][2]
The noble gases are the six elements that make up Group 18 of the periodic table: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). At one time, this family of elements was also known as the rare gases.
