The adsorption of very heavy elements on different surfaces Pd,Pt and Au, has been studied using relativistic molecular cluster calculation. We present various potential energy curves which allow the determination of binding energies and distances. To determine the adsorption geometry the calculations were made for different distances and position of the ad-atom relative to the surfaces. The comparison with the experimental results is made for Hg. Predictions of the adsorption of superheavy elements are intended.
