In earth's atmosphere, both oxygen and nitrogen gases comprise more than 20%. Nitrogen is closer to 78%, by weight, whereas O2 is currently just barely over 20%.
Nitrogen
You must be fishing for "water vapor". It varies a lot (the 'humidity'),but can be up to (not 'at least') about 4%.All other constituents of normal atmosphere are either much more ormuch less than than 4% .
Nitrogen is the gas that makes up about 78% of the Earth's atmosphere.
Argon and trace gases like neon, helium, and methane make up less than 1 percent of Earth's atmosphere.
Yes, there is more carbon dioxide in the Earth's atmosphere than argon. Carbon dioxide makes up about 0.04% of the atmosphere, while argon makes up about 0.93%.
The nitrogen and oxygen in Earth's atmosphere together account for a speck more than 99% of it..

There is much more nitrogen in earth's atmosphere than carbon dioxide. Nitrogen forms about 79%, while carbon dioxide makes up about 0.04%.
It is nitrogen and it makes more than 78% of the air.
