Which of the two ferrous or ferric ion has larger magnetic moment and why?

Explanation

To determine which ion, ferrous (Fe²⁺) or ferric (Fe³⁺), has a larger magnetic moment, we need to analyze their electronic configurations and the number of unpaired electrons in each ion.

### Step-by-Step Solution:

1. **Identify the Electronic Configuration of Iron (Fe)**:
- The atomic number of iron (Fe) is 26. Its electronic configuration is:
\[
\text{Fe: } [\text{Ar}] 3d^6 4s^2
