In a hydrogen atom, if energy of an electron in ground state is 13.6 eV, then that in the 2nd excited state is

Options

  1. A1.51 eV
  2. B3.4 eV
  3. C6.04 eV
  4. D13.6 eV

Correct answer

A. 1.51 eV

Step-by-step solution

2^ nd excited state will be the 3 rd energy level E _ n = 13.6 n ^2 eV or E = 13.6 9 eV =1.51 eV
