FAQs

Question: What are isotopes?
Answer: Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons.

Question: How does nuclear fission differ from nuclear fusion?
Answer: Nuclear fission is the splitting of a heavy nucleus into lighter nuclei, while nuclear fusion is the combining of light nuclei to form a heavier nucleus.
