Neon gas consist of individual, unbonded neon atoms due to the stable (octet) configuration, while chlorine exists as diatomic chlorine molecules to gain stability.
Stability of any atom will be defined on the basis of the electronic configuration or the number of valence shell electrons they have.
Hence due to stable configuration of neon it is present in the unbonded form.
