Argon, oxygen and nitrogen are three elemental gases that are components of air, which is a mixture of these and other gases. They are all colourless, and non-metals.
air has oxygen in it but also other gases, e.g. helium nitrogen.
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.
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
nitrogen, oxygen, and other gases
Air is made up of 78% nitrogen, 20.95% oxygen, 0.93% argon plus traces of other gases.
The atmosphere of the earth is the layers of air that surround the Earth. They contain nitrogen, oxygen, carbon dioxide, water vapor, and small percentages of other gases.
21% Oxygen, 78% Nitrogen and 1% Other Gases
The atmosphere of the Earth is composed of different gases. Some of these gases include nitrogen, oxygen, argon, and carbon dioxide.
78.08% nitrogen, 20.95% oxygen, 0.93% argon, carbon dioxide 0,04 %, etc.

Earth!!!! There is approximately 79% nitrogen, 20 % oxygen , and the other 1% is made up of other gases , ; carbon dioxide, water vapour, the noble gases, and trace amounts of sulphur dioxide, methane, ammonia.
