- Plutonium is made by the activation of uranium by neutrons. A shaped amount of refined uranium is lowered into an operating nuclear reactor, and the sample is bathed in the neutron flux of the operating reactor. Uranium atoms capture a neutron (via neutron absorption) and transform into plutonium.t is a fissile element used in most modern nuclear weapons. The most significant isotope of plutonium is 239Pu, with a half-life of 24,100 years. It can be made from natural uranium.

-  Different isotopes have different numbers of neutrons, ranging from  142 for Pu-236 to 150 for Pu-244. All the isotopes of plutonium has 94 protons and 94 electrons. For the number of neutrons of a specified isotope: number of neutrons = rounded atomic mass of the isotope-atomic number (or protons number).

Plutonium Isotopes Virtually any combination of plutonium isotopes -- the different forms of an element, having different numbers of neutrons in their nuclei -- can be used to make a nuclear weapon. Not all combinations, however, are equally convenient or efficient.t is this plutonium isotope that is most useful in making nuclear weapons, and it is produced in varying quantities in virtually all operating nuclear reactors. Plutonium containing high quantities of fissile material i.e. Pu-239 in the order of 90-95 %, is known as weapon-grade plutonium.

10 Plutonium Facts (Pu or Atomic Number 94) Pure plutonium is a silvery-white metal, although it quickly oxidizes in air to a dull finish. The atomic number of plutonium is 94, meaning all atoms of plutonium have 94 protons. It has an atomic weight around 244, melting point of 640°C (1183°F), and boiling point of 3228°C (5842°F). Plutonium oxide forms on the surface of plutonium exposed to air.

plutonium : a radioactive metallic element similar chemically to uranium that is formed as the isotope 239 by decay of neptunium and found in minute quantities in pitchblende, that undergoes slow disintegration with the emission of an alpha particle to form uranium 235, and that is fissionable with slow neutrons to yield atomic energy — see element table.

- Plutonium is unique among the elements in its physicochemical complexities by virtue of its position at a transitional location in the periodic table where the 5f electrons are at the border between delocalized (not associated with a single atom) and localized (associated with a single atom) behavior and it is considered one of the most complex of the elements. Plutonium also sits near the juncture where the actinide series transitions from main d-block element chemistry to rare earth like ...

- Plutonium Bomb. Plutonium-239 is a fissionable isotope and can be used to make a nuclear fission bomb similar to that produced with uranium-235. The bomb which was dropped at Nagasaki was a plutonium bomb. Not enough Pu-239 exists in nature to make a major weapons supply, but it is easily produced in breeder reactors.

- Not surprisingly, this production method is not the norm. Now, when einsteinium is required, plutonium is bombarded with neutrons in a reactor for several years until it is has taken on enough extra neutrons in the nucleus to pump it up to einsteinium.lements and Periodic Table History. Einsteinium was discovered in the debris of the first thermonuclear explosion which took place on a Pacific atoll, on 1 November 1952. Fall-out material, gathered from a neighbouring atoll, was sent to Berkeley, California, for analysis.

Radium 226 Ra is the most stable isotope of radium and is the last isotope in the (4 n + 2) decay chain of uranium-238 with a half-life of over a century. Its immediate decay product is the dense radioactive noble gas radon, which is responsible for much of the danger of environmental radium.adium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals.

Isotopes The total number of protons and neutrons in an atom is called its mass number. Chemical symbol of chlorine-35. The proton number is shown below the chemical symbol, and the mass number is shown above. In this example the atomic number is 17 and the mass number is 35. This means that each of these atoms has: 1  17 protons. 2  17 electrons.  35 - 17 = 18 neutrons.

PLUTONIUM Plutonium is named after the planet Pluto. The most stable isotopes of plutonium are plutonium-242 and plutonium-244. The half lives of these two isotopes are 376,300 years and 82,600,000 years respectively. The half life of a radioactive element is the time it takes for half of a sample of the element to break down.Consider the isotope plutonium-242, with its half life of 376,300 years. In 376,300 years (one half life), only half of a sample prepared today would still be plutonium-242.he half life of a radioactive element is the time it takes for half of a sample of the element to break down.
