Electronic Configurations of Superheavy Elements

We study electronic configurations of superheavy elements around one of islands of stabilities, from element 121 to 131, using the relativistic density functional theory with quantum electrodynamical corrections (Breit interaction) by MacDonald and Vosko. It is found that these corrections are important for studying electronic configurations of superheavy elements, and that g electrons in the atom first appear from element 126. We draw a table for the electronic configuration of elements including these superheavy elements.
