Nuclear fission and fusion
Question
- A. The splitting of a large unstable nucleus
- B. The joining of two light nuclei to form a heavier nucleus
- C. The release of energy from a single nucleus
- D. The process of neutron absorption
Answer
The correct answer is B: The joining of two light nuclei to form a heavier nucleus.
Explanation
The correct answer is B: The joining of two light nuclei to form a heavier nucleus. This supports the learning objective "(Physics only) Define nuclear fusion as the joining of two light nuclei to form a heavier nucleus." in Nuclear fusion (physics only) because it uses the correct atomic and nuclear radiation relationship for Nuclear fission and fusion. The other options are less suitable because they do not match the required Nuclear fusion (physics only) idea: The splitting of a large unstable nucleus; The release of energy from a single nucleus; The process of neutron absorption.
Common mistake
Misunderstanding Fusion Definition
Students often confuse nuclear fusion with nuclear fission, thinking both involve splitting nuclei.
