Is RnCl4 going to have 2 lones pairs

No, RnCl4 will not have 2 lone pairs. RnCl4 refers to a compound containing radon (Rn) and chlorine (Cl), and radon typically forms compounds where it has a coordination number of 4. In this case, RnCl4 would have 4 chlorine atoms bonded to the radon atom, but no lone pairs on the radon atom.
