Energy of the Electron & Energy Levels

The energy of a hydrogen atom in its ground state is $-13.6$ eV. The energy of the level corresponding to the quantum number $n = 2$ in the hydrogen atom is

Show answer and solution

Answer: (b)

$E_n = \frac{-13.6}{n^2}$ eV.
$E_2 = \frac{-13.6}{4} = -3.4$ eV
So the answer is (b) $-3.4$ eV.
