Effective atomic number of Fe in the complex` K_(3)[Fe(CN)_(6)]` is

Explanation

To find the effective atomic number (EAN) of iron (Fe) in the complex \( K_3[Fe(CN)_6] \), we can follow these steps:

### Step 1: Identify the oxidation state of Fe
In the complex \( K_3[Fe(CN)_6] \), we first need to determine the oxidation state of iron (Fe). The complex can be dissociated as follows:

\[ K_3[Fe(CN)_6] \rightarrow 3K^+ + [Fe(CN)_6]^{3-} \]
