Carbon.
Reason: In the form of diamond, carbon has extremely high thermal conductivity because its light atoms and very strong covalent bonds allow phonons (heat carriers in insulators) to travel very fast and with little scattering. Chlorine (a gas) and antimony (a semimetal/metalloid) conduct heat poorly by comparison; sodium is a metal and conducts heat, but not nearly as well as diamond.
