In a hydrogen atom, if the energy of an ...

In a hydrogen atom, if the energy of an electron in ground state is `- 13.6 eV`, then that in the `2^(nd)` excited state is :

A

`-1.51 eV`

B

`-3.4 e V`

C

`-6.04 eV`

D

`-13.6 eV`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) `2 nd` excited state means third energy level,
`E_3 = (E_1)/(3^2) = - (13.6)/(9) = - 1.51 eV`.
