Draw the Lewis structures of the following molecules and ions and ions and tell in which case/cases the octet
rule is violated ` CO_(2), SO_(2), BeCl_(2), NH_(3), AlCl_(3), PCl_(5), CO_(3)^(2-)`

Explanation

To draw the Lewis structures of the given molecules and ions, we will follow these steps:

### Step 1: Draw the Lewis Structure of CO₂
1. **Count the total valence electrons**: Carbon (C) has 4, and each Oxygen (O) has 6. Thus, total = 4 + 2(6) = 16 electrons.
2. **Arrange the atoms**: C is the central atom, bonded to two O atoms.
3. **Distribute electrons**: Form double bonds between C and each O to satisfy the octet rule.
4. **Final structure**:
