With reference to the coordination complex ion `[Fe(H_(2)O)_(6)]^(2+)` answer the following: (at. no. of Fe=26)
What is the oxidation number of the central metal atom?

Explanation

To find the oxidation number of the central metal atom (iron) in the coordination complex ion \([Fe(H_2O)_6]^{2+}\), we can follow these steps:

### Step 1: Identify the overall charge of the complex
The overall charge of the coordination complex ion \([Fe(H_2O)_6]^{2+}\) is given as \(+2\).

### Step 2: Assign the oxidation number to the central metal atom
Let the oxidation number of iron (Fe) be \(X\).
