In fission process_______.
Correct answer: B. massive nucleus splits to form smaller fragments
- A. massive nucleus join together
- B. massive nucleus splits to form smaller fragments
- C. both A & B
- D. None of these
Explanation
In nuclear fission, a heavy or massive nucleus splits into two or more smaller nuclei, releasing energy and usually neutrons. Joining nuclei is fusion, not fission. Students may choose both A and B because both are nuclear reactions, but only statement B defines fission.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
