Question

what is the name of the nuclear reaction that occurs in stars where protons combine to form larger nuclei? a fission b combustion c transmutation d fusion

Explanation:

• Fission: It is the splitting of a large nucleus into smaller nuclei, not the combination of protons.
• Combustion: It is a chemical reaction (involving electrons) and not a nuclear reaction.
• Transmutation: It is the process of changing one element into another, but the key here is the combination of protons (nuclear fusion concept).
• Fusion: Nuclear fusion is the process where light nuclei (like protons) combine to form a heavier nucleus, which is what occurs in stars.

Answer:

d. fusion
