What are the four main gases in our atmosphere?

Carbon dioxide oxygen nitrogen?
I searched it up and it says argon is the other one but we haven't learned about that yet
Would hydrogen be a main gas?

Believe your research.

Gases in atmosphere:

Nitrogen (N2) 78.084%
Oxygen (O2) 20.946%
Argon (Ar) 0.934%
Carbon dioxide (CO2) 0.0383 %
Neon (Ne) 0.001818 %
Helium (He) 0.000524 %
Methane (CH4) 0.0001745 %
Krypton (Kr) 0.000114%
Hydrogen (H2) 0.000055 %
There is also a varying amount of water vapor, depending on the altitude and conditions where it is measured

Yes, the four main gases in Earth's atmosphere are nitrogen, oxygen, argon, and carbon dioxide. Hydrogen is not considered one of the main gases in the atmosphere. However, it is present in very small amounts, usually less than 0.00005%. While hydrogen is an important element in the universe and can be found in trace amounts in the atmosphere, it is not considered one of the primary components of Earth's atmospheric composition.
