As par Bohr model, the minimum energy (in `eV`) required to remove an electron from the ground state of doubly ionized `Li` atom `(Z = 3)` is

A

`1. 51`

B

`13.6`

C

`40.8`

D

`122.4`

Text Solution

Verified by Experts

The correct Answer is:
D
`E = -Z^(2) xx 13.6 eV =- 9 xx 13.6 eV =-122.4 eV`
So ionisation energy `=+ 122.4 eV`
