Draw Lewis dot structure of `CO_3^(2-)` ion and find the formal charge on each oxygen atom.

Explanation

To draw the Lewis dot structure of the carbonate ion \( \text{CO}_3^{2-} \) and find the formal charge on each oxygen atom, follow these steps:

### Step 1: Determine the total number of valence electrons
- Carbon (C) has 4 valence electrons.
- Each oxygen (O) has 6 valence electrons, and there are 3 oxygen atoms.
- The ion has a -2 charge, which means we add 2 more electrons.

**Calculation**:
