Question

a process in which a large nucleus splits into two or more parts is called
______. (1 point)
beta decay
nuclear fusion
radioactive decay
nuclear fission

Explanation:

• Beta decay: A type of radioactive decay where a beta particle (electron or positron) is emitted from an atomic nucleus. It does not involve a large nucleus splitting into multiple parts.
• Nuclear fusion: The process where two or more atomic nuclei combine to form a heavier nucleus. This is the opposite of a large nucleus splitting.
• Radioactive decay: A general term for the process by which an unstable atomic nucleus loses energy by emitting radiation (such as alpha, beta, or gamma rays). It is a broader category, and not specifically about a large nucleus splitting into two or more parts.
• Nuclear fission: The process in which a large nucleus (such as uranium - 235) splits into two or more smaller nuclei, along with the release of a large amount of energy.

Answer:

nuclear fission
