Plutonium is an artificial chemical elements.
The isotopes 239Pu and 244Pu exist in nature (in extremely traces) in uranium deposits, as a result of nuclear reactions..
Polonium is an extremely rare chemical element, accompanying uranium ores; approx. 100 micrograms of polonium in one to (t) of uranium ore.
two inches per cm3
Plutonium is obtained in United States, United Kingdom, France, Russia, India, Pakistan, Japan, China.
Some plutonium chemical compounds; plutonium dioxide, plutonium nitride, plutonium carbide, plutonium nitrate, plutonium trifluoride, plutonium chloride, etc.
no, so don't use up too much
1. Plutonium is a reactive metal: the electronegativity of plutonium on Pauling scale is 1,28. 2. Plutonium has valences from 3 to 7.
Plutonium is an artificial chemical element; plutonium has not minerals, ores, deposits.
Because plutonium is very toxic, radioactive, flammable and explosive.
The Little Boy bomb had not plutonium.
Nuclear weapons with plutonium don't contain TNT.
The artificial plutonium was prepared for the first time in December 1940.The natural isotope Pu-244 is primordial, as old as the Earth but exist only in traces.
Plutonium is obtained in United States, United Kingdom, France, Russia, India, Pakistan, Japan, China.
Approx. 4 000 US $ for weapon-grade plutonium.
Radium: Plutonium does not occur naturally, and magnesium has a low density for a metal.
Plutonium, Iron
Approx. 4ooo US $ per gram for nuclear weapons quality plutonium; the price for nuclear reactors grade plutonium is lower.
Only a trace of plutonium is naturally found in the earth's crust. And it is always found with uranium because it is made by uranium's spontaneous fission, neutron release, and the subsequent neutron capture by another uranium nucleus to form the plutonium atom. Plutonium is not formed by the death of a star in a super nova like uranium is. Uranium is the heaviest element formed in that event. That's why there isn't any plutonium around as an ore. Just the trace amounts found with uranium. We're lucky there isn't a lot of plutonium around. It is highly toxic owing to its hightly radioactive nature.

1 plutonium (solid) gallon = 71,337 kg
Approx. 4 000 US $ for weapon-grade plutonium (in 2010).
