If U-238 splits into two even pieces, and each piece emits an alpha particle, what elements are produced?

  • Physics -

    alpha particle = 2 protons , 2 neutrons
    U238 has
    92 protons
    146 neutrons
    divide in half
    46 protons
    73 neutrons
    subtract 2 of each
    44 protons = Ru = Ruthenium
    71 neutrons, unlikely isotope of Ru, which generally would have about 57 neutrons
