In gamma ray emission from a nucleus.
- A Only the proton number changes
- B both, the proton number neutron and neutron number change
- C there is no change in the proton number and the neutron number
- D only the neutron number changes
Answer & Solution
Correct Answer
(C) there is no change in the proton number and the neutron number
Step-by-step Solution
Detailed explanation
Gamma emission involves the release of energy in the form of high-frequency photons from an excited nucleus to reach a lower energy state. Since no particles like protons or neutrons are ejected, the atomic number \((Z)\) and the mass number \((A)\) remain unchanged. There is no…
