they are present in very small amounts
air is a mixture of several gases: N2 78.5%, O2 21%, CO2 .3% and several gases in trace ammount
The atmosphere is made up of approx 79% Nitrogen, 20% Oxygen and 1% Argon and other trace gasses.
The atmosphere is composed of air. Air is a mixture of Nitrogen, Oxygen, Argon and other trace gases. The first three account for about 99% of the composition of air and are mentioned in the largest to smallest constituents.
Carbon dioxide 95.32%Nitrogen 2.7%Argon 1.6%Oxygen 0.13%Carbon monoxide 0.07%Water vapor 0.03%Nitric oxide .0013%Trace gases(including krypton and methane among others)Improved answer : Mercury has no significant atmosphere, but hasMINUTE traces of some gases.
The percentage of oxygen in air is 21%.
Trace gases are such because their concentrations are so much smaller than carbon dioxide. The trace gases that appear to be most important are N2O- nitrous oxide (laughing gas), CH4- methane, and CFC- chlorofluorocarbons.

argon i one
Oxygen, nitrogen, helium and trace amounts of argon. ( among other trace amounts )
"Trace elements" are elements which are present in a sample, but in relatively very small amounts. "Trace gasses" probably means gasses which are present in a sample, but in relatively very small amounts. the gases in earths atmosphere that take up less than 1% volume.
The Sun is composed mainly of hydrogen in helium, with trace amounts of a few metals and gases.
The earth's atmosphere contains trace gases, some of which absorb heat. These gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are referred to as greenhouse gases.
Nitrogen_____________________________________________________________________Our atmosphere is about 78% nitrogen and 21% oxygen. The remaining 1% is made up of a number of trace gases.
trace gases.
Different gases yes with some trace elements
