    • Plutonium is basically an actinide metal and it appears like silvery-gray.Continue Reading Chemistry – Plutonium – Notes For W.B.C.S Examination.
    • The element, which atomic number is ranging between 89 and 103, is known as actinide element.
    • The symbol of plutonium is ‘Pu’ and atomic number is ‘94.’
    • Plutonium normally possesses six allotropes.
    • Plutonium is named after ‘Pluto.’
    • Plutonium was first discovered in 1940, by a group of scientists namely Glenn T. Seaborg, Joseph W. Kennedy, Edwin M. McMillan and Arthur C. Wahl.

    Salient Features of Plutonium

    • Plutonium is a radioactive chemical element.
    • Plutonium when exposed to air, it gets tarnished and when it oxidized, it forms a dull coating.
    • Plutonium reacts with many elements including halogens, nitrogen, carbon, silicon, and hydrogen.
    • Because of fission process, neutrons get released and convert uranium-238 nuclei into plutonium-239.
    • Plutonium-239 and plutonium-241 both are fissile, and hence, they can sustain a nuclear chain reaction. It is very well applicable in nuclear weapons and nuclear reactors.
    • The melting point of plutonium is 640 0C and its boiling point is 3,228 0C.
    • The release of helium nucleus (a high-energy) is the most common form of radioactive decay for the plutonium.

    Occurrence of Plutonium

    • The plutonium naturally found only in trace amounts within the uranium deposits.
    • Plutonium is also extracted by burning the uranium (while developing nuclear energy).

    Alloys of Plutonium

    • Following are the major alloys of plutonium −
      • Plutonium–gallium is one of the important alloys of plutonium as well as of gallium.
      • Plutonium–gallium is used in the nuclear weapon pits.
      • Plutonium–gallium has the property of very low thermal expansion.
    • Some other alloys of plutonium are −
      • Plutonium–aluminum
      • Plutonium–gallium–cobalt
      • Plutonium–zirconium
      • Plutonium–cerium
      • Plutonium–uranium
      • Plutonium–uranium–titanium
      • Thorium–uranium–plutonium

    Compounds of Plutonium

    • Plutonium (IV) oxide – PuO2
    • Plutonium (III) chloride – PuCl3
    • Plutonium tetrafluoride – PuF4
    • Plutonium (III) fluoride
    • Plutonium hexafluoride
    • Plutonium hydride
    • Plutonium carbide
    • Plutonium borides

    Uses of Plutonium

    • The isotope plutonium-239 is one of the significant elements in developing the nuclear weapons.
    • Plutonium is used as a fuel in the nuclear power plants.
