What series of elements did Glenn Seaborg add to the periodic table?

Seaborg developed the chemical elements americium and curium while in Chicago. He managed to secure patents for both elements.

How did Seaborg organize his periodic table?

Seaborg recognized that the 14 elements heavier than actinium (89) are closely related to it and belong to a separate group in the periodic table, the actinide elements (now actinoid elements), analogous to the 14 elements heavier than lanthanum (57), the lanthanoids or rare earth elements.

What isotopes were created by Glenn Seaborg?

They are: plutonium (94), the most important element he co-discovered, used in the atomic bomb, instrumental in ending World War II, in which Russia and the USA were allies, and in nuclear reactors; americium (95), used in smoke detectors; curium (96); berkelium (97); californium (98); einsteinium (99); fermium (100); …

Which of the following elements was created by Glenn Seaborg’s research group at UC Berkeley?

This series of achievements culminated in 1974 with the creation of element 106, which was named seaborgium to honor Nobel Laureate Glenn Seaborg (1912-99), who played a key role in many of these discoveries at the laboratory.

What did Glenn Seaborg add to the periodic table?

On the basis of electron structures, in 1944 Seaborg proposed that a new row should be added to the periodic table. The new row would be placed below the row of elements known as the lanthanides. The elements in Seaborg’s new row would be called the actinides.

When did Glenn Seaborg come up with the actinide concept?

Glenn T. Seaborg, one of the researchers who synthesized transuranic elements, proposed the actinide concept in 1944 as an explanation for observed deviations and a hypothesis to guide future experiments. It was accepted shortly thereafter, resulting in the placement of a new actinide series comprising elements 89 ( actinium)…

How are actinium and lanthanum related on the periodic table?

Seaborg recognized that the 14 elements heavier than actinium (89) are closely related to it and belong to a separate group in the periodic table, the actinide elements (now actinoid elements), analogous to the 14 elements heavier than lanthanum (57), the lanthanoids or rare earth elements.

How did the actinides get their name from the periodic table?

Once they realised that Am and Cm were forming lanthanide-like +3 ions, they were able to separate them accordingly. Seaborg coined the term ‘actinides’, corresponding to ‘lanthanides’, named after the first element in the series, as a generic title for these elements.
