Question

Complete the nuclear equation 238 92U −→ ? + 234 90Th .

Answer 1

• 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.
