When a nucleus in an atom undergoes radioactive decay, the electronic energy levels of the atom (a) do not change for any type of radioactivity (b) change for α and β radioactivity but not for γ-radioactivity (c) change for α-radioactivity but not for others (d) change for β-radioactivity but not for others
Alpha and beta decay eject charged particles from the nucleus, altering its charge and its interactions with electrons, which in turn alter the electronic energy levels. Whereas Gamma radiation leaves the nucleus charge unchanged, and the electronic levels are not affected,
