Question

In a hydrogen atom, if energy of an electron in ground state is -13.6 eV, then that in the 2nd excited state is: (A) -1.51 eV (B) -3.4 eV (C) -6.04 eV (D) -13.6 eV

2nd excited state means third energy level. E3 =(E1/32) =(13.6/9) =-1.51 eV

Q. In a hydrogen atom, if energy of an electron in ground state is $- 13.6 e V$ , then that in the $2^{n d}$ excited state is:

$- 1.51 e V$

$- 3.4 e V$

$- 6.04 e V$

$- 13.6 e V$

2nd excited state means third energy level.
$E_{3} = \frac{E _{1}}{3 ^{2}} = \frac{13.6}{9} = - 1.51 e V$

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

−1.51eV

−3.4eV

−6.04eV

−13.6eV
