Question
In gamma ray emission from a nucleus
A.
only the proton number changes
B.
both the neutron number and the proton number change
C.
there is no change in the proton number and the neutron number
D.
only the neutron number changes
Answer :
there is no change in the proton number and the neutron number
Solution :
There is no change in the proton number and the
neutron number as the $$\gamma $$-emission takes place as a result of excitation or de-excitation of nuclei. $$\gamma $$-rays have no charge or mass.
