Nitrogen (78%) is the most abundant
then Oxygen (21%), Carbon Dioxide, water vapor, and finally trace elements
If you are talking about which one has the highest molecular mass, that would be Radon (222)

The component with the greatest Molecular Mass is Radon at a Mol.mass of 222. but is a very, very small constituent of the atmosphere.
Next comes Xenon and Krypton at 131 & 84 respectively, followed by CO2 at 44.
The mol.mass of air itself is 29.
Water vapour is 18

Carbon Dioxide

O2 = 32
N2 = 28
CO2 = 12+16+16 = 44
that is the most common stuff.
Argon is 40
(all of these are approximate due to isotopes and other factors.)

The more important in volume is Nitrogen
In molecular mass unfortinately Rn (radon) which is a radioactive noble gaz which can be very dangerous in non-aerated cellars
