Question

Which type of reaction does this diagram represent?

nuclear fission because an atom is splitting into two fragments
nuclear fusion because atomic nuclei combine to form a heavier nucleus

Answer 1

I can’t see the image — could you upload it or briefly describe what’s shown?

Meanwhile, here's how to tell them apart:
- If the diagram shows a single heavy nucleus splitting into two (or more) smaller nuclei and usually emitting neutrons → nuclear fission.
- If it shows two (or more) light nuclei joining to form a heavier nucleus → nuclear fusion.

Examples: U‑235 → Ba + Kr + neutrons is fission; 2H + 3H → 4He + n is fusion.
