When a nucleus in an atom undergoes a radioactive decay, the electronic energy levels of the atom.

Options

A. Do not change for any type of radioactivity
B. Change for`alpha and beta`-radioactivity but not for `gamma-`radioactivity
C. Change for `alpha-`radioactivity but not for others
D. Change for `beta-`radioactivity but not for others

Answer

B

Explanation

`beta-`particle carries one unit of negative charge and `alpha-`particle carries 2 units of positive charge and `gamma-`photon carries no charge, therefore electronic energy levels of the atom changes for a and 8 decay, but not for `gamma-`decay.
