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 process of emitting neutrons from a nucleus
- D. The release of energy from radioactive decay
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) Interpret simple diagrams of nuclei before and after fusion." 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 process of emitting neutrons from a nucleus; The release of energy from radioactive decay.
Common mistake
Misinterpreting Fusion Diagrams
Students often confuse the arrangement of nuclei in diagrams, misidentifying the reactants and products of fusion.
Carefully analyze the diagrams, noting the labels and the number of protons and neutrons in each nucleus to accurately identify the fusion process.
