PLUTONIUM - WikiVidi Documentary

Plutonium is a radioactive chemical element with symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous.  Plutonium was first produced and isolated on December 14, 1940 by a deuteron bombardment of uranium-238 in the 60-inch cyclotron at the University of California, Berkeley. First neptunium-238  was synthesized which subsequently beta-decayed to form this new element with atomic number 94 and atomic weight 238 . Since uranium had been named after the planet Uranus and neptunium after the planet Ne...
