In gamma ray emission from a nucleus:

  1. A
    both the neutron number and the proton number change
  2. B
    there is no change in the proton number and the neutron number
  3. C
    only the neutron number changes
  4. D
    only the proton number changes

Solution & Step-by-step Explanation

Gamma emission is the release of electromagnetic radiation (high-energy photons) from an excited nucleus. It allows the nucleus to transition to a lower energy state. Since photons have no charge and negligible mass, the atomic number and mass number remain unchanged. Thus, the number of protons and neutrons does not change.
