Energy is represented by the formula, $E _{ n }= E _1 \times \frac{ Z ^2}{ n ^2}$ for hydrogen-like species.
Energy is represented by the formula, $E _{ n }= E _1 \times \frac{ Z ^2}{ n ^2}$ for hydrogen-like species.
$E_1$ is the energy for the hydrogen first orbit and has a negative value.
As the $n$ increases, energy increases i.e., it becomes less negative. When $n=\infty$, the electron can have a maximum energy value of zero.
