| It's the chemical element named for the ninth planet from the sun |
| Pu doesn't refer to the smell of a reactor but to this fuel in it |
| Some breeder reactors produce Neptunium, along with this radioactive metal whose atomic number is 94 |
| This element, Pu, was first detected in a cyclotron at Berkeley in 1940 |
| The symbol of this radioactive element is Pu & it sounds like it's named after Mickey Mouse's dog |
| This, Pu-239, has a half-life of 24,100 years; yours would be a lot shorter if you touched it |
| As in planetary sequence, neptunium-239 emits a beta particle & becomes isotope 239 of this element |
| Pu! But this element-238 doesn't stink--it powers pacemakers |
| Logically, it was the radioactive transuranium metal discovered right after neptunium |
| Pu-244, an isotope of this, has a half-life of 80 million years, give or take |

| A naturally radioactive, silvery, metallic transuranic element, occurring in uranium ores and produced artificially by neutron bombardment of uranium. Its longest-lived isotope is Pu 244 with a half-life of 76 million years. It is a radiological poison, specifically absorbed by bone marrow, and is used, especially the highly fissionable isotope Pu 239, as a reactor fuel and in nuclear weapons. Atomic number 94 melting point 640C boiling point 3,235C specific gravity 19.84 valence 3, 4, 5, 6. See Table at element. |

|
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 1.5 metre (60 in) cyclotron at the University of California, Berkeley. First neptunium-238 (half-life 2.1 days) was synthesized which subsequently beta-decayed to form this new element with atomic number 94 and atomic weight 238 (half-life 87.7 years).
