The energy of a hydrogen atom in its ground state is `-13.6 eV`. The energy of the level corresponding to the quantum number n=5 is

A

`-0.54 eV`

B

`-5.40 eV`

C

`-0.85 eV`

D

`-2.72 eV`

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(n)=E_(1)Z^(2)/n^(2)" "E_(5)=-13.6xx((1)^(2))/((5)^(2))=-0.54 eV`
