The synthesis, via nuclear fusion reactions, of elements heavier than the actinides, allows one to probe the limits of the periodic table as a means of classifying the elements. In particular, deviations in the periodicity of chemical properties for the heaviest elements are predicted as a consequence of increasingly strong relativistic effects on the electronic shell structure. The transactinide elements have now been extended up to element 112 (ref. 8), but the chemical properties have been… Expand

Chemical investigation of hassium (element 108)
TLDR
Evidence that the chemical properties of hassium and its lighter homologue osmium are similar is provided, thus confirming that hassio exhibits properties as expected from its position in group 8 of the periodic table. Expand
Chemical characterization of bohrium (element 107)
TLDR
The chemical separation and characterization of six atoms of element 107 (bohrium, Bh), in the form of its oxychloride, is reported, finding that this compound is less volatile than the oxychlorides of the lighter elements of group VII, thus confirming relativistic calculations that predict the behaviour of bohrium to coincide with that expected on the basis of its position in the periodic table. Expand
Chemical characterization of element 112
TLDR
A more reliable chemical characterization of element 112, involving the production of two atoms of 283112 through the alpha decay of the short-lived 287114 and the adsorption of the two atoms on a gold surface, finds that element 112 is very volatile and, unlike radon, reveals a metallic interaction with the gold surface.
