78% Nitrogen,and 21% Oxygen
The most important elements in the Earth's atmosphere are N (nitrogen) and O (oxygen).
The most abundant gases in the Earth's atmosphere are nitrogen, which makes up about 78% of the atmosphere, and oxygen, comprising about 21%. Other gases, such as argon, carbon dioxide, and trace gases, make up the remaining 1%. Nitrogen plays a crucial role in maintaining atmospheric pressure and supporting life, while oxygen is essential for respiration in most living organisms.
Most gases in the atmosphere are found in the troposphere, which is the lowest layer of Earth's atmosphere, extending from the surface up to about 8 to 15 kilometers (5 to 9 miles) high. This layer contains roughly 75% of the atmosphere's mass and is where weather phenomena occur. Key gases such as nitrogen (78%) and oxygen (21%) are most concentrated in this region. Higher layers, like the stratosphere and mesosphere, have much lower densities of gases.
The most important constant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). These gases are crucial for supporting life and maintaining a stable climate on our planet. Other important constant gases include argon and carbon dioxide.
Hydrogen and helium make up the majority of Jupiter's atmosphere, with hydrogen being the most abundant element. These two elements make up more than 99% of the planet's atmosphere.
I'd say the most important gasses in the Earth's atmosphere are oxygen and water vapour.
Nitrogen and oxygen.
The most important thing that's a mixture of gasses is our atmosphere.
The three most common gasses in our atmosphere are: nitrogen 78%, oxygen 21%, and argon <1%.
Nitrogen and oxygen.
Nitrogen and oxygen are the two most predominant; nitrogen is about 79% of the air, and oxygen about 20%. The remaining 1% are various "trace" gasses, of which water vapor, carbon dioxide and argon are probably the most significant.

The atmosphere (air).
the most important gas is the gasses that we brethe.
Nitrogen (78%) and Oxygen (21%) are the two most abundant gasses in Earth's atmosphere.
Whe considered on a dry basis (water vapor removed) the atmosphere is made up of nitrogen (78%), oxygen (21%) and argon (1%). These numbers have been rounded somewhat and other elements and gasses in the atmosphere are present at in part per million levels. As an example carbon dioxide is present at 300 ppm (approx) or 0.03%.
Nitrogen, Oxygen,Hydrogen, and Carbon Di-oxide are the common Gases in the Atmosphere.
