Calculate the formal charge on each atoms in `CO_(4)^(2-)` (per -oxocarbonate ion) .

Explanation

To calculate the formal charge on each atom in the oxocarbonate ion \( CO_4^{2-} \), we will follow these steps:

### Step 1: Determine the Lewis Structure
First, we need to draw the Lewis structure for the oxocarbonate ion \( CO_4^{2-} \). The central atom is carbon (C), which is bonded to four oxygen (O) atoms. Two of these oxygen atoms will have double bonds with carbon, while the other two will have single bonds. The overall structure will be tetrahedral.

### Step 2: Count Valence Electrons
Next, we count the total number of valence electrons:
- Carbon has 4 valence electrons.
