Which of the following is the energy of a possible excited state of hydrogen?

A

`-3.4 eV`

B

`+ 6.8 eV`

C

`+13.6 eV`

D

`-6.8 eV`

Text Solution

Verified by Experts

The correct Answer is:

A

The energy of electron in the excited state `(n gt 1)` is negative.
By taking energy as-3.4 `eV_(i)`value of n is calculated as :
`n=sqrt((-13.6)/("Eexcited state"))=sqrt((-13.6)/(-3.4))=sqrt(4)=2`
`:.` It is the correct answer.
