Re: Expanding Atmosphere Types
H2O (water vapor or ocean planets)
Also, you could go to mixes of gases:
H/He (Jupiter and Saturn), H/He/CH4 (Uranus and Neptune), N2/O2 (Earth), N2/CH4 (Titan), etc.

Re: Expanding Atmosphere Types
...Nitroglycerin?
Or how about a species that relies on a radioactive planet to absorb energy?

Re: Expanding Atmosphere Types
I like the water and radiation ideas... not technically "atmospheres" but neither is "none", and it never hurts to be creative!
Of course, dolphins would argue that Earth is a water planet, not an oxygen planet...

So would Magellan.
Other atmospheres - Nitrous, Argon, Fluorine, Bromine
Add sodium as well.
From Google:
Three satellites of the outer planets possess atmospheres. Titan, a moon of Saturn, and Triton, a moon of Neptune, have nitrogen atmospheres. Another moon of Saturn, Enceladus, has an atmosphere composed primarily of water. Other bodies within the Solar System with extremely thin atmospheres are the Moon (sodium gas), Mercury (sodium gas), Europa (oxygen) and Io (sulfur). The dwarf planet Pluto also has an envelope of nitrogen and methane as it approaches close to the Sun, but these gases are frozen for most of its orbit.
