Predictions about the bizarre element could be put to the test once a facility for creating superheavy elements, under construction at Oganessian’s lab in Dubna, Russia, is up and running later this year.Įditor’s note: This story was updated February 12, 2018, to clarify how oganesson could be chemically reactive and on February 14, 2018, to correct the description of the element’s electron shells in the sidebar. This is at odds with some other heavy elements, in which the neutron rings are well-defined.įor Oganessian, these theoretical predictions about the element have come as a surprise. Unlike oganesson’s protons, which are predicted to be in distinct shells in the nucleus, the element’s neutrons are expected to mingle. Experimental evidence for a “bubble nucleus” has been found for an unstable form of silicon ( SN: 11/26/16, p. But the sheer number of oganesson’s protons - 118 - may help the particles overcome this force, creating a bubble with few protons at the nucleus’s center, researchers say. Protons inside an atom’s nucleus repel one another due to their like charges, but typically remain bound together by the strong nuclear force. At room temperature, scientists expect that these oganesson atoms could clump together in a solid, unlike any other noble gases. Immediately find any imaginable information about an element, calculate molar masses of any compounds you like, facilitate your overview with infographics and much more. Oganesson’s electron configuration could also let atoms of the element stick together, instead of just bouncing off one another as gas atoms typically do. As a result, the element could be chemically reactive. But because of how its electrons are configured, oganesson is the only noble gas that’s happy to both give away its electrons and receive electrons. On the periodic table, oganesson is grouped with the noble gases, which tend not to react with other elements.
