📌 Key Concepts to Remember:

- Metal + Non-metal → Ionic Bond
- Non-metal + Non-metal → Covalent Bond

You need to identify whether each element in the compound is a metal or non-metal, then apply the rule above to determine the bond type.

Here’s the completed table with explanations:

| Compound | Element 1 (metal or non-metal?) | Element 2 (metal or non-metal?) | Bond Type |
|----------|----------------------------------|----------------------------------|-----------|
| NO₂ | N = non-metal | O = non-metal | covalent |
| PI₃ | P = non-metal | I = non-metal | covalent |
| MgBr₂ | Mg = metal | Br = non-metal | ionic |
| CaO | Ca = metal | O = non-metal | ionic |
| H₂O | H = non-metal | O = non-metal | covalent |
| K₂O | K = metal | O = non-metal | ionic |
| AlF₃ | Al = metal | F = non-metal | ionic |
| O₂ | O = non-metal | O = non-metal | covalent |
| CuCl₂ | Cu = metal | Cl = non-metal | ionic |
| NO₂ | N = non-metal | O = non-metal | covalent |
| CO₂ | C = non-metal | O = non-metal | covalent |
| HF | H = non-metal | F = non-metal | covalent |
| Rb₂S | Rb = metal | S = non-metal | ionic |

✔ Explanation for Each:

#### 1. NO₂ — Nitrogen & Oxygen → both non-metals → Covalent
#### 2. PI₃ — Phosphorus & Iodine → both non-metals → Covalent
#### 3. MgBr₂ — Magnesium (metal) & Bromine (non-metal) → Ionic
#### 4. CaO — Calcium (metal) & Oxygen (non-metal) → Ionic
#### 5. H₂O — Hydrogen & Oxygen → both non-metals → Covalent
#### 6. K₂O — Potassium (metal) & Oxygen (non-metal) → Ionic
#### 7. AlF₃ — Aluminum (metal) & Fluorine (non-metal) → Ionic
#### 8. O₂ — Oxygen + Oxygen → same non-metal → Covalent
#### 9. CuCl₂ — Copper (metal) & Chlorine (non-metal) → Ionic
#### 10. NO₂ — Same as #1 → Covalent
#### 11. CO₂ — Carbon & Oxygen → both non-metals → Covalent
#### 12. HF — Hydrogen & Fluorine → both non-metals → Covalent
#### 13. Rb₂S — Rubidium (metal) & Sulfur (non-metal) → Ionic
#### 14. NBr₃ — Nitrogen & Bromine → both non-metals → Covalent
#### 15. Fe₂O₃ — Iron (metal) & Oxygen (non-metal) → Ionic
#### 16. CCl₄ — Carbon & Chlorine → both non-metals → Covalent

💡 Quick Tips:

- Metals: Usually found on the left side and center of the periodic table (Groups 1–2, transition metals like Fe, Cu, Al, etc.)
- Non-metals: Right side of the periodic table (C, N, O, F, P, S, Cl, Br, I, etc.) and Hydrogen (H) — even though it’s on the left, it behaves as a non-metal in bonding.
- Diatomic elements like O₂, N₂, Cl₂ are always covalent since they’re two identical non-metals sharing electrons.
