Predictions of adsorption behaviour of the superheavy element 112 Original Research Article

Predictions of chemical behaviour of element 112 with respect to that of Hg for gas-phase chromatography experiments have been made on the basis of fully relativistic four-component Density-Functional Theory (DFT) electronic structure calculations for intermetallic compounds of Hg and element 112. Using a model of localized adsorption, the equilibrium adsorption temperature for element 112 is predicted as somewhat a hundred degrees below that of Hg. This relation should be valid provided experiments are conducted in the same set up, under the same conditions. Thus, the reactivity of element 112 is expected to be somewhere between those of Hg and Rn.
