We know that nitrogen (at about 78%) and oxygen(at about 20 %) are the most abundant gases in the atmosphere. By inspection, it's obvious that there is only a couple of percent for all the other gases combined.
The second most abundant gas in the Earth's atmosphere is oxygen, which makes up about 21% of the gases in the atmosphere.
The most abundant nonmetal gases in the atmosphere are nitrogen, oxygen, and argon. Nitrogen makes up about 78% of the atmosphere, followed by oxygen at around 21%, and argon at approximately 0.93%.
The two most abundant gases in the Earth's atmosphere are nitrogen and oxygen. Nitrogen makes up about 78% of the atmosphere, while oxygen makes up about 21%.
