Atomic Reference Data for Electronic Structure Calculations, Electronic Configurations of the Elements | NIST

The article discusses the electronic configurations of neutral elements and their first cations from hydrogen to uranium. The data is sourced from the most recent compilation by the NIST Atomic Physics Division, with some configurations differing from older references. For cases where the previous compilation didn’t provide configuration identifications, the article references scientific literature for those specific cases. The ground electronic configurations are presented using a notation where [X] indicates all subshells associated with the noble gas X are fully occupied.
