    nobel gases or inert gases are always single atoms as atoms join up to allow them selves to be stable (full outter shells)

    Noble Gases have complete shell walls and therefore don't require to be joined to other atoms to be complete so they don't react with other elements, In this case, Radon is the one found as a single atom in nature if I'm correct.
