Calculate the formal charge on atoms in carbonate `(CO_(3)^(2-))` .

Explanation

To calculate the formal charge on the atoms in the carbonate ion \( \text{CO}_3^{2-} \), we will follow these steps:

### Step 1: Draw the Lewis Structure of \( \text{CO}_3^{2-} \)

1. **Count the total number of valence electrons**:
- Carbon (C) has 4 valence electrons.
- Each oxygen (O) has 6 valence electrons, and there are three oxygens.
- The ion has a -2 charge, which means we add 2 more electrons.
