Calculate the ionzation enthalpy of `Li` atom using Bohr's theory?

A

`122.4 eV`

B

`40.8 eV`

C

`81.6 eV`

D

Cannot be calculated

Text Solution

Verified by Experts

The correct Answer is:
D
The `Li` atom contains `3` electron, and Bohr's theory is applicable only to those atoms or ions which contains just one electron. However, using Bohr's theory, we can calculate the third ionization enthalpy of the `Li` atom or the first ionization enthalpy of the `Li^(2+)` ion.
