Plutonium
:This article is about the element. See also Archimedes Plutonium (internet user). ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Plutonium is a radioactive, metallic, chemical element. It has the symbol Pu and the atomic number 94. Its atomic weight is 244.06, its density 19,816 kg/m³. It is the element used in most modern nuclear weapons. The most important, albeit not most stable, isotope of plutonium is 239Pu, with a half-life of 24,110 years. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Plutonium is silvery in pure form, but has a yellow tarnish when oxidized. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Peculiarly, the metal goes through phases of contraction as its temperature is increased. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ The heat given off by alpha particle emission makes plutonium warm to the touch in reasonable quantities; larger amounts can boil water. It displays four ionic oxidation states in aqueous solution:
