For the first time, researchers have studied the chemistry of the element hassium, confirming its location on the periodic table. Hassium, with 108 protons in each atom, is the heaviest element yet to ...
In 1984, Peter Armbruster and Gottfried Münzenber along with their co-workers first produced hassium while performing an experiment at Gesellschaft für Schwerionenforschung in Germany. The team ...
La synthèse du hassium 270 a réussi en bombardant du curium 248 pendant plusieurs semaines avec des ions de magnésium-26. Le hassium 270 comporte 162 neutrons ; sa période radioactive atteint trente ...
This week's element is hassium, which has the atomic symbol, Hs, and the atomic number, 108. Its name comes from hassia, which is the Latin name for the German state of Hesse, home to the lab where it ...
Radioactive nuclei that hang around for a mere half-minute before falling apart hardly seem stable. Yet compared with the fleeting lifetimes of their superheavy atomic neighbors, the roughly 30-second ...
The discovery of Hs was reported in 1984 (ref. 11) with the identification of the nuclide 265 Hs with a half-life of T 1/2 = 1.5 ms (refs 11, 12). In 1996, the much longer-lived isotope 269 Hs, with a ...
Le hassium est un élément chimique transuranien qui a été ainsi baptisé en l'honneur du Land allemand de Hesse dans lequel il a été découvert. Le hassium est un métal radioactif supposé solide à ...
