The hydrogen-like species Ļi^(2+) is in ...

The hydrogen-like species `Ļi^(2+)` is in a spherically symmetric state `S_(1)` with one radial node. Upon absorbing light the ion undergoes transition to a state `S_(2)` The state `S_(2)` has one radial node and its energy is equal to the ground state energy of the hydrogen atom.
Energy of the state `S_(1)` in units of the hydrogen atom ground state energy is:

A

`0.75`

B

`1.50`

C

`2.25`

D

`4.50`

Text Solution

Verified by Experts

The correct Answer is:
C
`(E_(Li^(2+))(2s))/(E_(H))=(-(9)/(4)xx13.6)/(-13.6)=2.25`
