An extended periodic table was suggested by Glenn T. Seaborg in 1969. It is a logical extension of the principles behind the standard periodic table to include possible undiscovered chemical elements. All of the undiscovered elements are named by the International Union of Pure and Applied Chemistry (IUPAC) systematic element name standard of creating a generic name until it has been discovered, confirmed and an official name approved. Glenn Theodore Seaborg (April 19, 1912 â February 25, 1999) won the 1951 Nobel Prize in Chemistry for discoveries in the chemistry of the transuranium elements,[1] contributed to the discovery and isolation of ten elements, developed the actinide concept and was the first to propose the actinide series which led...
