Gas phase chemistry studies of transactinoid elements and the relativistic effects.

Original language description

Fast techniques based on gas-solid chromatography have played a major role in the experimental studies of transactinoid (Z >103) nuclides, which all possess half-lives less than a minute. To date, elements 104 to 106, the transition metals of groups 4 to6, have been chemically identified, and their (oxo)halides have been studied. The most challenging problem in transactinoids is the 'relativistic effects in chemical properties': the properties of new elements might not closely follow the trends observed for the lighter congeners in the appropriate groups, because at such high Z's atomic electrons reach relativistic velocities. Generally, one must first 'translate' the experimental data obtained with single atoms (molecules, ions) into the macroscopiccharacteristics like the boiling point, vaporization enthalpy, etc. Before considering the relativistic effects, one has to exclude the trivial origin of the differences (if any) from the properties of the congeners to identify the really
