Calculate the effective atomic number of the central metal atom `Cr(CO)_6` ​

Explanation

To calculate the effective atomic number (EAN) of the central metal atom in the complex `Cr(CO)6`, we can follow these steps:

### Step 1: Identify the Atomic Number of Chromium
The atomic number (Z) of chromium (Cr) is 24.

### Step 2: Determine the Oxidation State of Chromium
In the complex `Cr(CO)6`, carbon monoxide (CO) is a neutral ligand. Therefore, the overall charge of the complex is 0. Let the oxidation state of chromium be \( X \). Since CO is neutral, we can set up the equation:
\[ X + 6(0) = 0 \]
