When atomic nuclei get larger and larger the electrons have to go faster and faster. Once you reach a certain size calculations predict that the electrons have to go faster than the speed a light — a physical impossibility. Other calculations predict this will happen much later, however, around element While the four latest additions to the periodic table are highly radioactive and decay in less than a minute, scientists expect to find an island of stability centred around elements , or Researchers have already seen increasing stability of known superheavy elements when in isotopes with neutron numbers closer to the magic One chemistry professor received four month prison sentence for producing the drug in a university lab, while another was acquitted.

Joint Institute for Nuclear Research Particle accelerators create new elements by bombarding a heavy element target with highly accelerated lighter.

These atomic weights should be considered provisional since a new isotope with a longer half-life could be produced in the future. The Russian scientists who produced oganesson bombarded atoms of californium with ions of calcium for 1, hours. This resulted in three atoms of oganesson. Since only a few atoms of oganesson have ever been made, it has no practical uses outside of scientific study.
