Chemical properties of rutherfordium (Rf) and dubnium (Db) in the aqueous phase

Abstract

Abstract. Recent experimental studies of the chemical characterization of the first two transactinide elements, rutherfordium (Rf) and dubnium (Db), conducted atom-at-a-time in aqueous phases are reviewed. A short description on experimental techniques based on partition methods, specifically automated rapid chemical separation systems, is also given. Perspectives for aqueous-phase chemistry experiments on heavier elements are briefly discussed.

Introducing DDEC6 atomic population analysis: part 3. Comprehensive method to compute bond orders

“…120 Because of this short half-life, the chemistry of dubnium is not yet adequately explored. 146 Shown here is a computed dubnium hexauoride anion constrained to octahedral symmetry, but it is not yet known whether such a species actually exists in aqueous solutions. 146 The Db-F bond length (2.00Å) is longer than the S-F bond length (1.58Å).…”

Colloquium : Superheavy elements: Oganesson and beyond

“…In the following, we emphasize those chemical and physical properties of the superheavy elements that are strongly influenced by relativistic shell-structure effects leading to anomalies and often unexpected features when comparison is made to their lighter congeners in the periodic table (Schwerdtfeger and Seth, 1998). So far, chemical experiments at the atom-at-a-time scale have only been carried out for transactinides up to Hs (Nagame et al, 2016;Türler and Pershina, 2013) and for Cn and Fl (Eichler et al, 2008(Eichler et al, , 2010Yakushev et al, 2014), which all have reasonably long-lived isotopes in the time range of seconds.…”
