The history of the Periodic Table and its predecessors spans almost 200 years. The present IUPAC PT for Z = 1−118 is still adequate. The remarkable measurement for the Lr atom does not change the chemistry. The extensions up to Z = 172 are discussed and compared. New data for ions are presented. The “Madelung rule” is found to be surprisingly good even in that range.
