Energy of the Electron & Energy Levels question from NEET 1997 (AIPMT)

Q57NEET 1997 · AIPMTEasy

Energy of the Electron & Energy Levels

The energy of the ground electronic state of hydrogen atom is $-13.6$ eV. The energy of the first excited state will be

Show answer and solution

Answer: (c)

$E_n = \frac{E_1}{n^2}$ ; first excited state is $n = 2$ .
$E_2 = \frac{-13.6}{4} = -3.4$ eV
So the answer is (c) $-3.4$ eV.
