Noble gases exist as monatomic gases, which means that their molecules consist of a single atom.
A "Noble gas" can be defined as a gas which does not undergo chemical reactions. Examples of Noble gases are helium, Neon, Argon, Krypton, Xenon, and Radon.
Properties of noble gases:
Noble gases are the least reactive of all elements because they have eight valence electrons, which fill their outer energy level. That's why noble gases rarely react with other elements and form compounds.
Atoms of noble gases do not bond with other gases. Only helium exists as atoms of Helium, not as diatomic molecules. Helium does not form compounds with atoms of other elements.
