nitrogen: 78% oxygen: 21% trace gases: 1%
Nitrogen makes up 78% of the atmosphere, not 98%.
Nitrogen (78 %) and oxygen (21 %).
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.
These gases are nitrogen, oxygen and argon.
