Plutonium Basic Facts Atomic Number: 94 Symbol: Pu Atomic Weight: 244.0642 Discovery: G.T. Seaborg, J.W. Kennedy, E.M. McMillan, A.C. Wohl (1940, United States). The first sample of plutonium was produced by deuteron bombardment of uranium in a cyclotron at the University of Cali...
Plutonium is element atomic number 94 with element symbol Pu. It is a radioactive metal in the actinide series. Pure plutonium metal is silvery-gray in appearance, but it glows red in the dark because it is pyrophoric. This is a collection of plutonium element facts. Plutonium Basic Facts ...
The element symbol for plutonium is Pu, rather than Pl, because this was a more amusing, easily remembered symbol. The element was synthetically produced by Glenn T. Seaborg, Edwin M. McMillan, J.W. Kennedy, and A.C. Wahl at the University of California at Berkeley in 1940–1941. The ...
