Explanation:
Gamma emission is the release of high-energy electromagnetic radiation (photons) from a nucleus transitioning from an excited high-energy state to a lower, stable energy state. Gamma rays carry no mass and no electrical charge. Therefore, the emission of a gamma ray does not alter the number of protons (atomic number) or the total number of nucleons (mass number) of the atom.
