### Understanding Lattice Energy

**Instructions:**
In each row, pick the compound with the bigger lattice energy.

**Note:** Lattice energy is always greater than zero.

**Comparison Table:**

| Which compound has the bigger lattice energy? |
|-----------------------|
| **BaS**     | BaCl₂ |
| ○                   |     ○     |
| **MgI₂**    | NaI |
| ○                   |     ○     |
| **BeS**     | BeO |
| ○                   |     ○     |

- In the first row, the selected compound is **BaS**.
- In the second row, no compound is currently selected.
- In the third row, no compound is currently selected.

**Guide:**

1. **Lattice Energy:** It is a measure of the strength of the bonds in an ionic compound. Higher lattice energy corresponds to a stronger bond, indicating greater stability of the compound.
2. **Factors Affecting Lattice Energy:**
   - **Charge of Ions:** Higher charges generally lead to higher lattice energies.
   - **Size of Ions:** Smaller ions usually result in greater lattice energies since the ions can get closer together, increasing the electrostatic attraction.

**Explanation of Table:**
- **BaS vs. BaCl₂:**
  - Factor to consider: The charge and the size of the ions.
  - Answer: Compound with a higher lattice energy is **BaS**.
  
- **MgI₂ vs. NaI:**
  - Factor to consider: The charge of Mg²⁺ vs. Na⁺.
  - Still needs to be selected based on the higher charge of Mg²⁺ compared to Na⁺.

- **BeS vs. BeO:**
  - Factor to consider: The charge and the size of the ions.
  - Still needs to be selected based on comparisons of lons' size and charge.

Make sure to analyze the ionic charges and sizes properly when selecting the compound with higher lattice energy.
