What determines a noble gas?

Noble gasses are chemically inert (non-reactive) because their valence shells are full, and they therefore do not react with other elements, including themselves. Because they are inert, and unlike most other gasses, noble gasses are monatomic, meaning they exist in gaseous form as single atoms (unlike Oxygen (O2), Hydrogen (H2), etc.)

Noble gasses include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). Note that Radon, while noble, is also radioactive.
