The hexaquo manganese(II) ion contains five unpaired electrons, while the hexacyanoion contains only one unpaired electron. Explain using the crystal field theory.

Explanation

To explain the difference in the number of unpaired electrons in the hexaquo manganese(II) ion and the hexacyanomanganate(II) ion using crystal field theory, we will follow these steps:

### Step 1: Identify the Central Metal and its Oxidation State
- The central metal in both complexes is manganese (Mn).
- The oxidation state of manganese in the hexaquo manganese(II) ion is +2, as indicated by the Roman numeral II.
- In the hexacyanomanganate(II) ion, the oxidation state is also +2.

### Step 2: Determine the Electronic Configuration
