== ​ __** ☆•°o.O ƤԼƲƬƠƝƖƲM O.o°• ☆ ​**__  //Plutonium [ chemical symble pu ] is a highly toxic radioactive element. It was manerfactured in 1941, and took a year for it to acummilate to be actuly __visable__ as it was so small you could not see it, but now, 2010 there is so much of it we can not get rid of it, we have, indeed, created a monster. Plutonium is now known as the most dangerous element on the periodic table. Its only uses are for energy of the nuclears: Nuclear explosives and neclear power etc.

Name of Element : Plutonium Symbol: Pu Atomic Number: 94 Atomic Mass: (244.0) amu Melting Point: 639.5 °C - 912.65 °K Boiling Point: 3235.0 °C - 3508.15 °K Number of Protons/Electrons: 94 Number of Neutrons: 150 Crystal Structure: Monoclinic Density @ 293 K: 19.84 g/cm3

Plutonium is __verry__ expensive to produce. It's current price is at least $4000 per __gram__ but ranges up to nearly $6000 U.S dollars. Thats more than one houndred and thirty times the price of gold ! Though you must be licenced to buy or hold possesion so unless you are a recognized government in the United Nations or an energy company with a nuclear reactor you will not be able to get hold of it, although you would not want to. With the prices as they are clearly one must have good reason to justify its use. ( Sorce - // [|//http://hypertextbook.com/facts/2008/AndrewMorel.shtml//])

// Plutonium is so powerfull that the first atomic bomb was dropped on the city of Nagasaki, Japan, in 1945, killing an estimated 73,900 people with only 6.1 kg of plutonium, ( equivalent to 20,000 tonnes of TNT. ) //

Plutonium was discovered by Glenn T. Seaborg, J. W. Kennedy, E. M. McMillan and A. C. Wahl in 1941. It is considered a man made element but latly scientists have found trace amounts in naturly ocuring plutonium in highly unusial circumstances. Plutonium-239 is made by bombarding uranium-238 with neutrons in a nuclear reactor.

Not only is plutonium used for neclear bombs and power, but it is used to power all long range space missions. This is due to the fact that plutonium has a half life that ranges from 87.74 to 80 million years depending on what type of plutonium is being used. All other forms of energy are not advanced enough, so the heat is used to power the electrical systems. Plutonium is so powerfull that one pound of plutonium can produce as much energy as 24,315,600 cubic feet of coal.
