Here it is - Doc Emmit Brown's element: PLUTONIUM
Plutonium was the second transuranium element of the actinide series to be discovered. By far of greatest importance is the isotope 239Pu, which has a half-life of more than 20000 years. One kilogram is equivalent to about 22 million kilowatt hours of heat energy. The complete detonation of a kilogram of plutonium produces an explosion equal to about 20000 tons of chemical explosive. The various nuclear applications of plutonium are well known. The isotope 233Pu was used in the American Apollo lunar missions to power seismic and other equipment on the lunar surface. Plutonium contamination is an emotive environmental problem.
•Name: Plutonium
•Symbol: Pu
•Atomic number: 94
•Atomic weight: [ 244 ]
•Standard state: solid at 298 K
•CAS Registry ID: 7440-07-5
•Group in periodic table:
•Group name: Actinoid
•Period in periodic table: 7 (actinoid)
•Block in periodic table: f-block
•Color: silvery white
•Classification: Metallic
Historical information
Plutonium was discovered/synthesized by Glenn T. Seaborg , J. W. Kennedy, E. M. McMillan, A. C. Wahl at 1940 in USA,by deuteron bombardment of uranium in a cyclotron (a device used to accelerate atomic particles) at Berkeley, California, USA. Named after the...er, former...planet Pluto. Plutonium was the second transuranium element of the actinide series to be discovered. In 1808 plutonium was suggested as a name for element 56 but Sir Humphrey Davy's original name of barium for element 56 still stands.
