Chemistry of superheavy elements.
The number of chemical elements has increased considerably in the last few decades. Most excitingly, these heaviest, man-made elements at the far-end of the Periodic Table are located in the area of the long-awaited superheavy elements. While physical techniques currently play a leading role in these discoveries, the chemistry of superheavy elements is now beginning to be developed. Advanced an...
متن کاملChemistry of the superheavy elements.
The quest for superheavy elements (SHEs) is driven by the desire to find and explore one of the extreme limits of existence of matter. These elements exist solely due to their nuclear shell stabilization. All 15 presently 'known' SHEs (11 are officially 'discovered' and named) up to element 118 are short-lived and are man-made atom-at-a-time in heavy ion induced nuclear reactions. They are iden...
متن کاملExploring the island of superheavy elements
Over the last thirty years, experimentalists have, so to speak, launched an expedition to explore the predicted “island of superheavy elements”—a region of increasingly stable nuclei around atomic number 114 (Fig. 1). So far they have reported, on average, the discovery of one new element every two and a half years. Now, a Russian-American collaboration headed by Yuri Oganessian at the Joint In...
متن کاملShell Structure of the Superheavy Elements
Ground state properties of the superheavy elements (SHE) with 108≤Z≤128 and 150≤N≤192 are investigated using both the Skyrme-Hartree-Fock method with a density-independent contact pairing interaction and the macroscopic-microscopic approach with an average Woods-Saxon potential and a monopole pairing interaction. Detailed analysis of binding energies, separation energies, shell effects, single ...
متن کاملAdsorption Studies with Homologs of Superheavy Elements
In preparation of chemical studies with superheavy elements around Z = 114, the adsorption behavior of these elements and their lighter homologs on different metals has been predicted based on (semi-)empirical models and extrapolations (see e.g. [1, 2]). Adsorption studies with SHE homologs were performed on various metals, especially metals of group 10 and 11 (see e.g. [3]). The experimental r...
