Choose an option
Show full solutionCorrect option: B
Correct answer
B–3.4 eV
Step-by-step explanation
Energy(En) =
where n = 1, 2, 3, 4, ......
For hydrogen Z = 1 and excited state starts from n = 2
So putting n = 2
E2 = = -3.4 eV
where n = 1, 2, 3, 4, ......
For hydrogen Z = 1 and excited state starts from n = 2
So putting n = 2
E2 = = -3.4 eV
