Extending the Periodic Table
The periodic table now extends to element 118, Oganesson, and scientists are attempting to go further. Below is part of a Segre chart, proton number on the y-axis and neutron number of the x-axis, from a report from the Japanese Superheavy Element Laboratory, RIKEN Nishina Center, RIKEN.
The diagram shows various nuclear reactions, for example: 232Th + 40Ar to make 272Hs.
