Question

Which statement best describes the difference between nuclear fission and nuclear fusion reactions?

Answer 1

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy

Answer 2

They are both nuclear reactions that produce energy.

• Fission is the splitting of heavy, unstable nucleus into two lighter nuclei.
• Fusion is the process where two light nuclei combine together (this process releases a vast amount of energy)
