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=(3)^(2)xx13.6eV`
`=-9xx13.6eV=-122.4eV`
So, ionisation energy is +122.4 eV.
