What term describes the nuclear process in which a heavy atomic nucleus splits into two or more smaller nuclei, releasing a large amount of energy?

Explanation

Nuclear fission is the process in which a heavy atomic nucleus, such as uranium, splits into smaller nuclei after being struck by a neutron, releasing a substantial amount of energy along with additional neutrons that can trigger further fission reactions. This chain reaction is the basis for both nuclear power plants, which harness the released energy to generate electricity, and early atomic weapons. Fission differs fundamentally from fusion, which combines rather than splits atomic nuclei. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
