What is the main difference between nuclear fusion and nuclear fission?
Correct Answer: Nuclear fusion combines light nuclei, while nuclear fission splits heavy nuclei.
- Step 1: Understand that nuclear fusion is a process where two light atomic nuclei come together to form one heavier nucleus.
- Step 2: Recognize that nuclear fission is a process where one heavy atomic nucleus splits into two or more lighter nuclei.
- Step 3: Remember that fusion releases energy when the light nuclei combine, while fission releases energy when the heavy nucleus splits.
- Step 4: Note that fusion occurs in stars, like the sun, while fission is used in nuclear power plants and atomic bombs.
