A comparative study of the chemical properties of element 120 and its homologs

The electronic structure and energetics were calculated for molecules of binary compounds of element 120 and its homologs with common elements strongly differing in chemical properties. The calculations were performed within the framework of the relativistic density functional theory using the model of precision two-component atomic core pseudopotentials. The results obtained show that all the examined compounds of element 120 should differ from the corresponding compounds of the known heavy metals of the second group (Sr-Ra) in lower strengths and larger lengths of chemical bonds. Therefore, one can suppose that element 120 will be, on the whole, more inert chemically than its nearest homologs.
