Plutonium is an artificial element, discovered in 1940 at Berkeley Laboratories by Glenn Seaborg and Edwin McMillan; plutonium is obtained by nuclear reactions: 23892U + 10n ----→ 23992U --- β- -→ 23993Np --- β- -→ 23994Pu
Plutonium is a transuranic radioactive chemical element with the symbol Pu and
atomic number 94. It is an actinide metal silvery-gray appearance that tarnishes
when exposed to air, and forming 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 expand the sample up to
70% in volume, which in turn flake off as a powder that can spontaneously ignite. It is
radioactive and can accumulate in the bones. These properties make the handling of
plutonium dangerous.
Plutonium is the heaviest primordial element by virtue of its most stable isotope, Plutonium-244,
whose half-life of about 80 million years is just long enough for the element to be found in
trace quantities in nature. Plutonium is mostly a byproduct of nucloear reactions in reactors
where some of the neutrons released by the fission process convert uranium-238 nuclei into
plutonium. Both plutonium-239 and plutonium-241 are fissile, meaning that they can sustain
a nuclear chain reaction, leading to applications in nuclear weapons and nuclear reactors.
Plutonium-240 exhibits a high rate of spontaneous fission, raising the neutron flux of any
sample containing it. The presence of plutonium-240 limits a sample's usability for weapons
or reactor fuel, and determines its grade. Plutonium-238 has a half-life of 88 years and
emits alpha particles. It is a heat source in radioisotope thermoelectric generators, which
are used to power some spacecraft. Plutonium isotopes are expensive and inconvenient to
separate, so particular isotopes are usually manufactured in specialized reactors.
Plutonium is an artificial chemical element, radioactive, solid metal at room temperature, toxic, member of the actinides group, usd in nuclear weapons or as nuclear fuel in nuclear energetic reactors.
The name plutonium is derived from the name of the dwarf planet Pluto.
The name plutonium is derived from the name of the Latin god Pluto.
The symbol Pu was chosen by convention: the first letter of the name and the third.
Plutonium is a man made chemical element.
* Plutonium 244 is a natural isotope, very rare, probably obtained by stellar nucleosynthesis.
* Plutonium 244 is also obtained as a residue of nuclear weapons explosins.
Plutonium comes from uranium.
the (then) planet pluto.
Who cares??!! get on with ur life
Plutonium is not corrosive.
Weapons grade plutonium has min. 90 % plutonium 239 and max. 1 % plutonium 240.
Plutonium has 20 isotopes (from Pu 228 to Pu 247).
Plutonium is a metal.
Plutonium .
The name of the chemical element plutonium (Pu) is derived from the name of the dwarf planet Pluto.
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
Countries with plutonium facilities: USA, United Kingdom, France, Russia, India, Japan, China, Pakistan.
Uranium 238 is bombarded by neutrons, and forms Neptunium 238. Neptunium decays to form Plutonium 238.
Some plutonium chemical compounds; plutonium dioxide, plutonium nitride, plutonium carbide, plutonium nitrate, plutonium trifluoride, plutonium chloride, etc.
The name of the chemical element plutonium is derived from the name of the dwarf planet Pluto. And the name of the planet is derived from the name of the Roman god of the underworld.
Uranium is a natural element extracted from ores. Plutonium is an artificial element obtained in a nuclear reactor by nuclear reactions from uranium 238.
Examples are: plutonium metal, isotope Pu-238, plutonium dioxide, plutonium sulfide, plutonium nitrate, plutonium carbide etc.
Examples: PuO2, plutonium nitrate, plutonium carbide, plutonium chloride, plutonium fluoride etc.
Plutonium chemical properties:- plutonium is a reactive metal: the Pauling electronegativity is 1,28- plutonium is flammable- plutonium has six allotropes- plutonium in compounds has valences from 2 to 7- plutonium is very toxic
There's no plutonium here. I haven't even seen any plutonium, recently.
The name plutonium is derived from the name of the dwarf planet Pluto; dwarf planet Pluto is after planet Neptune in the Solar system and plutonium is after neptunium in the periodic table of Mendeleev.
