Question

how is nuclear fusion different from nuclear fission? fission produces energy but fusion does not. fusion produces energy but fission does not. in fission, the product is a larger atomic nucleus. in fusion, the product is a larger atomic nucleus.

Explanation:

To determine the correct answer, we analyze each option:

• The first (yellow) option: Fission does produce energy (e.g., in nuclear power plants), so this is incorrect.
• The second (blue) option: Fission also produces energy, so this is incorrect.
• The third (orange) option: In nuclear fission, a large atomic nucleus splits into smaller nuclei. Wait, no—wait, the option says "In fission, the product is a larger atomic nucleus"—no, that's wrong. Wait, maybe I misread. Wait, the green option: "In fusion, the product is a larger atomic nucleus"—fusion is the combining of small nuclei (like hydrogen isotopes) to form a larger nucleus (like helium), releasing energy. Fission is splitting a large nucleus (like uranium) into smaller ones. So let's re - evaluate:
• Yellow: "Fission produces energy but fusion does not." Wrong, both produce energy (fusion in stars, fission in reactors).
• Blue: "Fusion produces energy but fission does not." Wrong, fission produces energy.
• Orange: "In fission, the product is a larger atomic nucleus." Wrong, fission splits large nuclei into smaller ones.
• Green: "In fusion, the product is a larger atomic nucleus." Correct, because fusion is the process of combining two or more light atomic nuclei (e.g., hydrogen) to form a heavier (larger) atomic nucleus (e.g., helium), while fission is the splitting of a heavy nucleus into lighter ones.

Answer:

The correct option is the green - colored one with the text "In fusion, the product is a larger atomic nucleus." (Assuming the green option is the fourth one, but based on the description, the correct statement about the difference between fusion and fission is that in fusion, the product is a larger atomic nucleus, while fission splits a large nucleus into smaller ones, and both produce energy.)
