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

A

`+13.6eV`

B

`-6.8eV`

C

`-3.4eV`

D

`+638eV`

Text Solution

Verified by Experts

The correct Answer is:
C
Energy of excited state is negative and corresponds to n more than 1 for hydrogen.
`E=-(13.6Z^(2))/(n^(2))eV`
Z=1, First excited state n=2
`:.E=-3.6/(2^(2))=-3.4eV`
