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 other
D. change for `beta-`radioactivity but not for other

Answer

b

Explanation

`alpha-beta` particle carries one unit of negative charge an `alpha-`particle carries 2 units of positive charge and `gamma` (particle) carries no charge therefore electronic energy levels of the atom charges for `alpha` and `beta` decay but not for `gamma-`decay.
