Answer:

  • The required piece will be He.

Chemical Equation:

                     238 92U −→ 4 2 He + 234 90Th

Fission reaction:

  • When heavy nucleous absorb additional light particles usually neutron and it splits into two or more than pieces.Such a process is known as fission reaction.
  • Like in this case, Uranium split into thorium and Helium.
