Their outer energy levels are completely filled with electrons.

A filled valence shell (2 electrons for He, and 8 for Ne, Ar, Kr, Xe, Rn) makes them very stable and largely unreactive — hence they rarely form compounds (though heavier noble gases like xenon can form compounds under special conditions).
