Answer;
C) atomic nucleus into two smaller parts
Fission is the splitting of an atomic nucleus into two smaller parts.
Explanation;
- Nuclear fission is the process which involves the splitting of a large atomic nucleus into smaller nuclei. During the process the nucleus of an atom splits into two or more smaller nuclei as fission products.
- During nuclear fission heavy atomic nucleus, such as that of uranium or plutonium, is split into two fragments of roughly equal mass. This is coupled by the release of a large amount of energy. In nuclear fission the nucleus of an atom breaks up into two lighter nuclei.
