Give reason, `Mn^(2+)` ion is more paramagnetic than `Fe^(2+)` ion.

Text Solution

AI Generated Solution

To determine why the \( \text{Mn}^{2+} \) ion is more paramagnetic than the \( \text{Fe}^{2+} \) ion, we will analyze their electronic configurations and the number of unpaired electrons in each ion. ### Step-by-Step Solution: 1. **Understand Paramagnetism**: - Paramagnetism is a property of materials that have unpaired electrons. The more unpaired electrons an ion has, the stronger its paramagnetic nature. 2. **Find the Electronic Configuration**: ...
