Contribution of Glenn T. Seaborg in the Discovery of Plutonium

Glenn T. Seaborg was an American nuclear chemist who played a major role in the discovery of plutonium in 1940.
Seaborg and his team at the University of California, Berkeley, were studying the element uranium when they bombarded it with deuterons (heavy hydrogen nuclei).
This bombardment resulted in the formation of a new element, which was later identified as plutonium.
Plutonium was found to be a fissile material, meaning that it could undergo nuclear fission, releasing a great amount of energy.
This discovery led to the development of the atomic bomb during World War II.
Seaborg also played a key role in the discovery of other transuranium elements, including americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, and nobelium.
For his work in nuclear chemistry, Seaborg was awarded the Nobel Prize in Chemistry in 1951.
