Who changed the Periodic Table arrangement?
The Periodic Table was most recently reconfigured by Nobel Prize winner Glenn Seaborg, an American Professor of Chemistry born in 1912. He discovered plutonium and all of the other transuranium elements; during the 1940s, he changed the arrangement of the Periodic Table to accommodate them.Source:Western Oregon University: A Brief History of the Development of Periodic TableAll Periodic Tables: The History of the Periodic TableNobel Prize: Glenn T.
