Biography

Glenn Theodore Seaborg was born April 19 1912 in Ishpeming Michigan. He was an American scientist who won the 1951 Nobel Prize in Chemistry for "discoveries in the chemistry of the transuranium elements.

He spent most of his career as an educator and research scientist at the University of California Berkeley where he became the second Chancellor in its history and served as a University Professor.

Contributions to chemistry

In 1940 Seaborg in collaboration with Edwin McMillan Joseph Kennedy and Arthur Wahl isolated plutonium (element 94).

Seaborg was the principal or co-discoverer of ten elements

Plutonium - It is considered a man-made element and radioactive metal with Atomic Number 94.

Americium - It is a transuranic radioactive chemical element that has the symbol Am and atomic number 95.

Curium – It is a transuranic radioactive chemical element with the symbol Cm and atomic number 96.

Berkelium – It is a transuranic radioactive chemical element with the symbol Bk and atomic number 97.

Californium – It is a radioactive metallic chemical element with the symbol Cf and atomic number 98.

Einsteinium – It is a synthetic element with the symbol Es and atomic number 99.

Fermium – It is a synthetic element with symbol Fm and atomic number 100.

Mendelevium – It is a synthetic element with the symbol Md and the atomic number 101.

Nobelium – It is a synthetic element with the symbol No and atomic number 102.

Seaborgium – It is a synthetic chemical element with the symbol Sg and atomic number 106

Seaborg also developed more than 100 atomic isotopes and is credited with important contributions to the chemistry of plutonium. Early in his career Seaborg was a pioneer in nuclear medicine and developed numerous isotopes of elements with important applications in the diagnosis and treatment of diseases most notably iodine-131 which is used in the treatment of thyroid disease.

He developed actinide concept which placed the actinide series beneath the lanthanide series on the periodic table Seaborg proposed the placement of super-heavy elements in the

Transactinide and

Superactinide series.
