Nuclear Fission
  • Nuclear fission is the process of splitting
    atoms, or fissioning them.
  • The Chemical Equation for Nuclear Fission is as
    follows
  • 235U 1 n -gt 2 n 92KR 142Ba ENERGY
  • The mass seems to be the same on both sides of
    the reaction
  • 235 1 2 92 142 236
  • The mass of an atom is more than the sum of the
    individual masses of its protons and neutrons,
    which is what
  • those numbers represent.

Splitting The Uranium Atom
  • Uranium is used in nuclear reactors and in
    certain types of atomic bombs. The specific
    isotope used is 235U. When a stray neutron
    strikes a 235U nucleus, it is absorbed into it.
    This creates 236U. 236U is unstable and this
    causes the atom to fission. The fissioning of
    236U can produce over 20 different products. The
    products' masses always add up to 236. The
    following equations show the different products
    that can be produced when 235U fissions
  • 235U 1 neutron    2 neutrons 92Kr 142Ba
    ENERGY
  • 235U 1 neutron    2 neutrons 92Sr 140Xe
    ENERGY
