A lithium atom has electrons. Assume the following simple picture of the atom Two electron moves close to the nucleus making up a spherical cloud it and the third moves outside the cloud in a circular orbit . Bohr's model can be used for the motion of this third electron but` n = 1` state are not available to it. Calculate the ionization energy of lithium in ground state using the above picture.

Explanation

To calculate the ionization energy of lithium in the ground state using the given model, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Lithium Atom Configuration**:
- Lithium (Li) has 3 electrons and 3 protons in its nucleus.
- According to the problem, two electrons are close to the nucleus forming a spherical cloud, while the third electron is in a circular orbit outside this cloud.
