Explain the structure of `CO_(3)^(2-)` ion in terms of resonance
(b) Explain the resonance structures of `CO_(2)` molecule .

Explanation

To explain the structure of the carbonate ion \((CO_3)^{2-}\) in terms of resonance, we need to follow these steps:

### Step-by-Step Solution:

1. **Identify the Valence Electrons**:
- Carbon (C) has 4 valence electrons.
- Each Oxygen (O) has 6 valence electrons, and there are three Oxygens, contributing a total of \(3 \times 6 = 18\) electrons.
- The ion has a \(2-\) charge, which means we add 2 more electrons.
