Superheavy Elements Exploring Limits Periodic Table

To date, the periodic table contains 118 elements, from which the majority are found in nature having been produced by natural processes in the universe. Only the superheavy elements (Z≥104) have not been found in nature so far, and they must be created by humans in accelerator facilities. The production and detection of these elements involves extremely difficult challenges to scientists, due to their short life times (milliseconds up to one minute) and low production rates (one atom/month up to one atom/day). This talk will include answers to many questions about these new elements such as: How do you create superheavy elements? Since their life time is short, how do you study them? Where do they fit into the periodic table? Why do we need them? Dr Lotte Lens is a nuclear physicist and chemist from the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany where she has spent the last 5 years studying the volatile element flerovium (Fl, Z=114) which was discovered in 1998 and has a half life of a few seconds.
