Question

In gamma ray emission from a nucleus :

• A. both the neutron number and the proton number change
• B. there is no change in the proton number and the neutron number
• C. only the neutron number changes
• D. only the proton number changes

Answer 1

The correct option is B there is no change in the proton number and the neutron number

In gamma decay, the exited nuclear state is converted into non-exited daughter Nuclei. There is no change in the number of protons and neutrons in the parent nucleus and daughter nucleus.

Hence, no change in proton and neutron number.
