Glenn Theodore Seaborg (April 19, 1912 - Feb. 25, 1999) was an American chemist. Scientists had discovered that elements could be transmuted in a kind of modern alchemy by firing subatomic particles at them in particle accelerators. He was also recruited by the Manhattan Project and the former U.S. The first hint the world had of the existence of americium came not in a paper for a distinguished journal, but on a children's radio quiz in 1945. February 26, 1999. He added ten elements to the periodic table—amounting to almost a tenth of all the elements known. While at Chicago, Seaborg and his team discovered two more elements, americium (95) and curium (96). In 1969, Glenn T. Seaborg proposed the following extended periodic table to account for undiscovered elements from atomic number 110 to 173, including the “super-actinide” series of elements (atomic numbers 121 to 155). Glenn T. Seaborg Biographical G lenn Theodore Seaborg was born in Ishpeming, Michigan, on April 19, 1912. Log in. In February 1941, Seaborg and his colleagues produced plutonium-239 through the bombardment of uranium. He went on to identify several more of the radioactive “transuranium” elements—so named for their position following uranium in the periodic table—and received a Nobel Prize in 1951.
This experimental achievement proved to be a major It was also in Chicago, in 1944, that Seaborg developed the "actinide concept" of heavy element electronic structure, probably his single greatest contribution to science. annalv23aa 06/06/2017 Chemistry High School +5 pts. His work on the electronic structure of elements led to the periodic table being rewritten. Sep 12, 2014 - Explore ann9robinson's board "Glenn T. Seaborg and Charts" on Pinterest. This photograph of Glenn Seaborg appears in my Photographic Periodic Table Poster representing seaborgium, which is named after him.
At the age of 10 he moved with his family to California, in 1929 he graduated at David Starr Jordan High School in Los Angeles as valedictorian of his class. seaborgium, synthetic, element, sg, 106, chemistry, science, glenn seaborg, seaborg, periodic table, periodic table of elements, tile, square. He is credited as co-discoverer of plutonium and other elements up to element 102. Join now. Seaborg's Periodic Table .
He was awarded the Nobel Prize in Chemistry in 1951. The name seaborgium, with its chemical symbol of "Sg," was announced at the 207th national meeting of the American Chemical Society in San Diego. ... My theory required a major realignment of the periodic table of the elements (you can predict an element's chemistry by its position on the table). Log in.

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."
