Let the potential energy of hydrogen atom in the ground state be zero. Then its total energy in the first excited state will be

A

27.2 eV

B

23.8eV

C

13.6eV

D

10.2eV

Text Solution

Verified by Experts

The correct Answer is:
D
Energy is ground state `=-13.6 eV`
Energy in 1st excited state `= -(13.6)/(4) = -3.4eV`
`:.` Energy `=-3.4 + 13.6 = 10.2eV`
