Specify the oxidation number of the metals in the following coordination entities `[Cr(NH_3)_3Cl_3]`

Explanation

To determine the oxidation number of chromium in the coordination compound \([Cr(NH_3)_3Cl_3]\), we can follow these steps:

### Step 1: Identify the components of the coordination compound
- The central metal atom is chromium (Cr).
- The ligands are ammonia (NH₃) and chloride ions (Cl⁻).

### Step 2: Assign oxidation states to the ligands
- Ammonia (NH₃) is a neutral ligand, so it has an oxidation state of 0.
