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.
nitrogen, oxygen, carbon dioxide,argon are the most abundent gases. nitrogen being the biggest at around 76%.
In order (approximate values)
These gases are nitrogen, oxygen and argon.
oxygen
hydrogen and nitrogen (I think)
These gases are: nitrogen (78,084 %), oxygen (20,9476 %), argon (0,934 %), carbon dioxide (0,0314).
These gases are nitrogen, oxygen and argon.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
Nitrogen & oxygen.
Nitrogen and oxygen, respectively, are the two most abundant gases in the earth's atmosphere.
Hydrogen, Nitrogen, Oxygen
Nitrogen and Oxygen
on ancient Earth, nitrogen, water vapor, carbon dioxide, and methane were probably the most abundant gases in the atmosphere.
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
The Abundant gases are Nitrogen, Helium, and other gases in the Secondary Atmosphere.
Nitrogen N2 78.08% Oxygen O2 20.95%
Helium is the most abundant of the Noble gases in the universe.
Most abundant - Water Vapor
Nitrogen
There are many gases in the atmosphere. The two most common gases found in the atmosphere however, are nitrogen and oxygen.
