Which process splits a nucleus into two or more fragments?

Explanation:
Splitting a nucleus into two or more fragments is fission. In fission, a heavy nucleus such as uranium or plutonium becomes unstable and divides into lighter nuclei, often after absorbing a neutron, and it typically releases extra neutrons along with a large amount of energy. This is different from fusion, where light nuclei combine to form a heavier nucleus; from transmutation, which changes one element into another via nuclear reactions; and from ionization, which involves removing electrons rather than altering the nucleus. The action of dividing the nucleus into smaller pieces is the hallmark of fission.
