Which divalent metal ion has maximum paramagnetic character among the first transition metals? Why?

Explanation

To determine which divalent metal ion has the maximum paramagnetic character among the first transition metals, we need to analyze the electronic configurations of the divalent ions of these metals and count the number of unpaired electrons. Here's a step-by-step solution:

### Step 1: Identify the first transition metals
The first transition metals include:
- Scandium (Sc)
- Titanium (Ti)
- Vanadium (V)
- Chromium (Cr)
