Calculate the radii of 2nd Bohr orbit of`Li^(2+)`

Explanation

To calculate the radii of the 2nd Bohr orbit of the \( \text{Li}^{2+} \) ion, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values**:
- For the \( \text{Li}^{2+} \) ion, the atomic number \( Z \) is 3 (since lithium has 3 protons).
- The principal quantum number \( n \) for the second orbit is 2.
