    A solid, silvery-grey, radioactive transuranic chemical element that can be split when bombarded with neutrons. It is found in tiny amounts in uranium ores but is usually produced artificially in nuclear reactors.

    • Plutonium-239 is a key isotope used in nuclear reactors and weapons.
    • The production of plutonium requires a controlled nuclear reaction.
    • Scientists handle plutonium with extreme caution due to its high radioactivity.
