The chemical element of atomic number 94, a dense silvery radioactive metal of the actinide series, used as a fuel in nuclear reactors and as an explosive in nuclear fission weapons. Plutonium only occurs in trace amounts in nature but is manufactured in nuclear reactors from uranium-238
a solid silvery grey radioactive transuranic element whose atoms can be split when bombarded with neutrons; found in minute quantities in uranium ores but is usually synthesized in nuclear reactors; 13 isotopes are known with the most important being plutonium 239
Plutonium is a transuranic radioactive chemical element with the chemical symbol Pu and atomic number 94. It is an actinide metal of silvery-white appearance that tarnishes when exposed to air, forming a dull coating when oxidized. ...
In ancient Greek religious , a Ploutonion (Πλουτώνιον), Latinized as Plutonium, was a sanctuary dedicated to the god Plouton ("Pluto"), often in a location that produced and thus representing an entrance to the Underworld.
A radioactive metallic element chemically similar to uranium.
a heavy, man-made, radioactive metallic element. The most important isotope is Pu-239, which has a half-life of 24,000 years. Pu-239 can be used in reactor fuel and is the primary isotope in weapons. One kilogram is equivalent to about 22 million kilowatt-hours of heat energy. ...
is a key nuclear material used in modern nuclear weapons and is also present as a byproduct in certain reprocessed fuels used in some nuclear reactors. Pu-239 is also produced in uranium reactors as a byproduct of fission of U-235.
A transuranic element, formed in a nuclear reactor by neutron capture. It has several isotopes, some of which are fissile and some of which undergo spontaneous fission, releasing neutrons. ...
a heavy, radioactive, man-made, metallic element (atomic number 94) used in the production of nuclear energy and the explosion of nuclear weapons; its most important isotope is fissile plutonium-239, produced by neutron irradiation of uranium-238.
An artificial radioactive isotope that can be fabricated into nuclear fuel and fissioned in a reactor to produce energy. Some plutonium isotopes also can be used in nuclear weapons.. Others can't.
Symbol:"Pu" Atomic Number:"94" Atomic Mass: (244)amu. Plutonium is one of the elements in the actinide series of inner transition elements. It may be classified as a rare earth element. It is a radioactive and unstable element and you will find it in nuclear devices and reactors. ...
A very heavy element formed when uranium-238 absorbs neutrons. Like uranium, it has two principal isotopes that are fissile.
A highly toxic, heavy, radioactive metallic element. There are 15 isotopes of plutonium, of which only five are produced in significant quantities: plutonium-238, -239, -240, -241, and -242. ...
A highly lethal radioactive element created from uranium to build atomic bombs starting in World War II.
A man-made fissile element. Pure plutonium is a silvery metal that is heavier than lead. Material rich in the plutonium-239 isotope is preferred for manufacturing nuclear weapons, although almost any plutonium can be used.
(in plutonium (Pu) (chemical element))
a metallic element that is used esp. as a fuel in the production of nuclear power, and in nuclear weapons.

An artificially produced element that is fissile and radioactive. It is created when an atom of uranium-238 captures a slow neutron in its nucleus.
A silvery-white radioactive metal that exists as a solid under normal conditions. It is produced when uranium absorbs a neutron. Small amounts of plutonium occur in nature, but large amounts have been artificially produced in nuclear reactors. ...
