Calculate the number of unpaired electrons in `Cr^(3+)` and `V^(3+) ` ions.

Explanation

To calculate the number of unpaired electrons in the `Cr^(3+)` and `V^(3+)` ions, we will follow these steps:

### Step 1: Determine the Atomic Numbers
- Chromium (Cr) has an atomic number of 24.
- Vanadium (V) has an atomic number of 23.

### Step 2: Write the Electron Configurations
- The electron configuration for Chromium (Cr) is:
