The synthesis of element 102 was then claimed in April 1958 at the University of California, Berkeley by Albert Ghiorso, Glenn T. Seaborg, John R. Walton and Torbjørn Sikkeland.

The group of elements is more diverse than the lanthanides and therefore it was not until 1945 that Glenn T. Seaborg proposed the most significant change to Mendeleev's periodic table, by introducing the actinides.

Further anomalous elements in this series have been predicted by Glenn T. Seaborg, and are categorised as the “ island of stability .”

This concept, proposed by University of California professor Glenn Seaborg, explains why superheavy elements last longer than predicted.

Those elements listed with asterisks (*) are named after the University, Professors Lawrence and Seaborg.

This concept, proposed by University of California professor Glenn Seaborg, explains why superheavy elements last longer than predicted.

With Glenn T. Seaborg, he shared the Nobel Prize in Chemistry in 1951 for " discoveries in the chemistry of the transuranium elements.

After the war, Seaborg and Ghiorso returned to Berkeley, where they and colleagues used the 60 " Crocker cyclotron to produce elements of increasing atomic number by bombarding exotic targets with helium ions.

Scientists affiliated with the department and the nearby Lawrence Berkeley National Laboratory are responsible for the discovery of sixteen elements, including Berkelium, named after the city, and Seaborgium, named after Nobel laureate and former department chair Glenn Seaborg.

Chemistry Nobelist Glenn T. Seaborg who first proposed the actinide concept which led to the acceptance of the actinide series also proposed the existence of a transactinide series ranging from element 104 to 121 and a superactinide series approximately spanning elements 122 to 153.

During his Manhattan Project research in 1943 Glenn T. Seaborg experienced unexpected difficulty isolating Americium ( 95 ) and Curium ( 96 ).

Lawrence's secretary, Helen Griggs married the future Nobel Prize in Chemistry winner, Glenn T. Seaborg, in 1942, as the three of them made their way to work on the Manhattan Project in Chicago, Illinois.

In the early 1940s, Seaborg moved to Chicago to work on the Manhattan Project.

He was also the chairman of the Committee on Political and Social Problems regarding the atomic bomb ; the committee consisted of himself and other scientists at the Met Lab, including Donald J. Hughes, J. J. Nickson, Eugene Rabinowitch, Glenn T. Seaborg, J. C. Stearns and Leó Szilárd.

Landmark status for EBR-I was granted by President Lyndon Johnson and Glenn T. Seaborg on August 25, 1966.

The concept of nuclear spallation was first coined by Nobelist Glenn T. Seaborg in his doctoral thesis on the inelastic scattering of neutrons in 1937.

For the next four years he worked with Professor Glenn T. Seaborg at University of California, Berkeley, mostly on nuclear taxonomy.

The Regents, acting on the recommendation of Chancellor Glenn T. Seaborg and President Clark Kerr, authorized the formation of the Laboratory in 1959.

More recently, the chairman of the Atomic Energy Commission, Dr. Glenn T. Seaborg, `` admitted '' to a news conference in Las Vegas, Nevada, that the US might fall behind Russia ( he apparently meant in weapons development ) if the Soviets continue to test in the atmosphere while we abstain.

Americium was first produced in 1944 by the group of Glenn T. Seaborg at the University of California, Berkeley.

Although americium was likely produced in previous nuclear experiments, it was first intentionally synthesized, isolated and identified in late autumn 1944, at the University of California, Berkeley by Glenn T. Seaborg, Leon O. Morgan, Ralph A. James, and Albert Ghiorso.

At the time, the periodic table had been restructured by Seaborg to its present layout, containing the actinide row below the lanthanide one.

After the discovery of americium isotopes < sup > 241 </ sup > Am and < sup > 242 </ sup > Am, their production and compounds were patented listing only Seaborg as the inventor.

Although very small amounts of berkelium were possibly produced in previous nuclear experiments, it was first intentionally synthesized, isolated and identified in December 1949 by Glenn T. Seaborg, Albert Ghiorso and Stanley G. Thompson.

Curium was first intentionally produced and identified in July 1944 by the group of Glenn T. Seaborg at the University of California, Berkeley.

In 1950, Glenn T. Seaborg, Albert Ghiorso, and Stanley G. Thompson bombarded < sup > 241 </ sup > Am with helium ions, which produced atoms with an atomic number of 97 and which closely resembled the neighboring lanthanide terbium.

Mendelevium ( for Dimitri Ivanovich Mendeleev, surname commonly transliterated into Latin script as Mendeleev, Mendeleyev, Mendeléef, or even Mendelejeff, and first name sometimes transliterated as Dmitry or Dmitriy ) was first synthesized by Albert Ghiorso, Glenn T. Seaborg, Gregory R. Choppin, Bernard G. Harvey, and Stanley G. Thompson ( team leader ) in early 1955 at the University of California, Berkeley.

The American name of seaborgium for element 106 was also objectionable to some, because it referred to American chemist Glenn T. Seaborg who was still alive at the time this name was proposed.

The PUREX process was invented by Herbert H. Anderson and Larned B. Asprey at the Metallurgical Laboratory at the University of Chicago, as part of the Manhattan Project under Glenn T. Seaborg ; their patent " Solvent Extraction Process for Plutonium " filed in 1947, mentions tributyl phosphate as the major reactant which accomplishes the bulk of the chemical extraction.

* The Radiation Laboratory ( now Lawrence Berkeley National Laboratory ) at the University of California, Berkeley, led principally by Edwin McMillan, Glenn Seaborg, and Albert Ghiorso, during 1945-1974:

** Plutonium is first synthesized in the laboratory by a team led by Glenn T. Seaborg and Edwin McMillan at the University of California, Berkeley.

He moved to the radar research at the Massachusetts Institute of Technology and Glenn T. Seaborg finished the work.

Ghiorso's ability to develop and produce these instruments, as well as a variety of electronic tasks, brought him into contact with the nuclear scientists at the University of California Radiation Laboratory at Berkeley, in particular Glenn Seaborg.

During a job in which he was to install an intercom at the lab, he met two secretaries, one of whom married Seaborg and the other, Wilma Belt, who became Albert's wife of 60 + years.
