As an electron makes a transition from an excited state to the ground state of a hydrogen-like atom/ion

Options:

Answer:

Solution:

$U = - \frac{e^{2}}{4 {πε}_{0} r}$
$U$ = potential energy

$K = \frac{e^{2}}{4 {πε}_{0} r}$
$K$ =kinetic energy

$E = U + K = - \frac{e^{2}}{8 {πε}_{0} r}$
$E$ =total energy

$∴$ As electron de-excites from an excited state to ground state, $K$ increases but $U$ and $E$ decrease.
