Saturn is basically one big atmosphere - as far as we know, there is no real surface to the planet. Its composition is nearly all H2; the rest is approximately: * H2: 96.3±2.4% * He: 3.25±2.4% * CH4: 0.45±0.2% * NH3: 0.0125±0.075% * HD: 0.011±0.0058% * C2H6: 0.0007±0.00015% Besides this, aerosols of ammonia ice, water ice, and ammonia hydrosulfide exist in the atmosphere. So as to answer your queastion the out atmosphere doesn't contain a gass but aersols of ammonia ice, water ice, and ammonia hydrosulfide. Saturn is in effect one big atmosphere with no land just gas and the ices listed above. The primary gas found on Saturn is H2.
hydrogen and helium with some ammonia, methane, and water vapor.
The atmosphere of Saturn is mostly made up of hydrogen, which accounts for 97% of its composition. Helium makes up most of the remaining 3%, except for about 0.05% of methane.
It has a thick atmosphere, mostly made p of gases.
hydrogen/helium possibly rocks or ice (hazy clouds are surrounding) white ammonia covers the whole planet
Saturn's gases are hydrogen,neon,helium,hydrocarbens,and nitrogen...

Nitrogen and oxygen make up the largest percentage of the atmosphere.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
The two main gases that make up the atmosphere of Uranus are hydrogen and helium. The atmosphere also contains ammonia and methane.
