    'In 1944, Seaborg formulated the 'actinide concept' of heavy element electronic structure which predicted that the actinides – including the first eleven transuranium elements – would form a transition series analogous to the rare earth series of lanthanide elements. Called one of the most significant changes in the periodic table since Mendeleev's 19th century design, the actinide concept showed how the transuranium elements fit into the periodic table."

    Between 1944 and 1958, Seaborg identified eight elements – americium (95), curium (96), berkelium (97), californium (98), einsteinium (99), fermium (100), mendelevium (101), and nobelium (102). Element 106, seaborgium, bears his name.'
