Helium (He).

Reason: Helium has a filled 1s2 valence shell, giving it a very stable, inert electronic configuration and very high ionization energy, so it almost never bonds. Carbon, phosphorus and sodium all commonly form chemical bonds. (Only under extreme or specialized conditions are any stable helium compounds known.)
