“…Experimental conditions for these experiments and the number of fission tracks recorded in the mica detectors are given in Table 3 In this second series of 1969 chemical experiments, [33] in essential correspondence with the previous series, [31] the distribution of fission tracks in the mica detector column (Fig. 11) was stated to "imply a half-life of somewhat less than one second.…”

“…Since the 1960's several successful experiments with elements Rf, Db, Sg, Bh, Hs, and Cn have been performed [4][5][6][7][8][9][10][11][12][13][14]. The given references represent an important subset of all available experiments on the chemistry of these elements.…”

Summary. The chemical investigation of E113 is likely to become soon feasible. The determination of chemical properties of carrier-free amounts of the lighter homologues of element 113, especially indium and thallium, allows designing experimental set-ups and selecting experimental conditions suitable for performing these studies. Here, we present investigations of the interaction of indium species with quartz and gold surfaces. Deposition temperatures as well as enthalpies of adsorption were determined for indium T dep = 739 ± 20• C (−∆H ads (In) = 227 ± 10 kJ mol −1 ) and for indium hydroxide T dep = 250 ± 20• C (−∆H ads (InOH) = 124 ± 10 kJ mol −1 ) respectively, on quartz. In case of adsorption of indium on a gold surface only a lower limit of the deposition temperature was established T dep > 980• C (−∆H ads (In) ≥ 315 ± 10 kJ mol −1 ). Investigations of macroscopic amounts of indium in thermosublimation experiments at similar experimental conditions were instrumental to establish a tentative speciation of the observed indium species.

“…Although early gas-phase studies of the halides of Rf and Ha (35,36 ), suggested that they behaved like their lighter group 4 and 5 homologues, only SF activity was detected, Figure 10. Photo of microcomputer-controlled ARCA II (mini-ARCA).…”

“…These are especially suitable for studies of short-lived isotopes because the time-consuming step of evaporating a liquid sample is avoided. I. Zvara et al (35,36 ) at Dubna pioneered the use of the thermochromatographic method to study the halides of Rf and Ha. Unfortunately, in these early studies only SF activity was measured, so the identity of the element being studied is uncertain and the results cannot be considered definitive.…”

FutureMore "In-Depth" Chemical Studies Chemistry beyond Seaborgium? 93 NpIn keeping with the goal of the Viewpoints series of the Journal of Chemical Education, this article gives a 75-year perspective of the chemistry of the heaviest elements, including a 50-year retrospective view of past developments, a summary of current research achievements and applications, and some predictions about exciting, new developments that might be envisioned within the next 25 years. A historical perspective of the importance of chemical separations in the discoveries of the transuranium elements from neptunium (Z = 93) through mendelevium (Z = 101) is given. The development of techniques for studying the chemical properties of mendelevium and still heavier elements on the basis of measuring the radioactive decay of a single atom ("atom-at-a-time" chemistry) and combining the results of many separate experiments is reviewed. The influence of relativistic effects (expected to increase as Z 2 ) on chemical properties is discussed. The results from recent atom-at-a-time studies of the chemistry of the heaviest elements through seaborgium (Z = 106) are summarized and show that their properties cannot be readily predicted based on simple extrapolation from the properties of their lighter homologues in the periodic table. The prospects for extending chemical studies to still heavier elements than seaborgium are considered and appear promising.
