Naming Chemical Compounds Worksheet with a table for students to complete with correct information.

Let's solve this Naming Chemical Compounds Worksheet step by step. We'll identify the individual ions in each compound and then determine the correct name of the compound based on standard chemical nomenclature rules.

🔹 Key Rules for Naming:

- Ionic compounds: Name the cation first, then the anion.
- For transition metals with variable charges (e.g., Fe, Cu, Sn, Pb), use Roman numerals to indicate oxidation state.
- Polyatomic ions have specific names (e.g., SO₄²⁻ = sulfate, CO₃²⁻ = carbonate, PO₄³⁻ = phosphate, OH⁻ = hydroxide, C₂H₃O₂⁻ = acetate).
- Cations are usually metals or NH₄⁺ (ammonium).
- Anions end in "-ide" if monatomic; polyatomic ions have their own names.

Now, let’s fill out the table:

| Formula | Individual Ions | Name of the Compound |
|-------------------|----------------------------------------------|------------------------------------------|
| NH₄Cl | NH₄⁺, Cl⁻ | Ammonium chloride |
| ZnCO₃ | Zn²⁺, CO₃²⁻ | Zinc carbonate |
| FePO₄ | Fe³⁺, PO₄³⁻ | Iron(III) phosphate |
| LiOH | Li⁺, OH⁻ | Lithium hydroxide |
| CuBr₂ | Cu²⁺, Br⁻ | Copper(II) bromide |
| SnO₂ | Sn⁴⁺, O²⁻ | Tin(IV) oxide |
| Ag₃N | Ag⁺, N³⁻ | Silver nitride |
| Pb₃P₂ | Pb⁴⁺, P³⁻ | Lead(IV) phosphide |
| CaI₂ | Ca²⁺, I⁻ | Calcium iodide |
| K₂SO₃ | K⁺, SO₃²⁻ | Potassium sulfite |
| Fe₂(SO₄)₃ | Fe³⁺, SO₄²⁻ | Iron(III) sulfate |
| Cu(C₂H₃O₂)₂ | Cu²⁺, C₂H₃O₂⁻ (acetate) | Copper(II) acetate |
| AgC₂H₃O₂ | Ag⁺, C₂H₃O₂⁻ (acetate) | Silver acetate |
| Co₃N₂ | Co²⁺, N³⁻ | Cobalt(II) nitride |

✔ Explanation of Each Entry:

1. NH₄Cl
- NH₄⁺ is ammonium ion, Cl⁻ is chloride → Ammonium chloride

2. ZnCO₃
- Zn²⁺, CO₃²⁻ → Zinc carbonate (Zn has fixed charge)

3. FePO₄
- PO₄³⁻ needs 3+ charge → Fe³⁺ → Iron(III) phosphate

4. LiOH
- Li⁺, OH⁻ → Lithium hydroxide

5. CuBr₂
- Two Br⁻ ions → total -2 → Cu must be +2 → Copper(II) bromide

6. SnO₂
- O²⁻ × 2 = -4 → Sn must be +4 → Tin(IV) oxide

7. Ag₃N
- N³⁻ → three Ag⁺ ions → Ag⁺ → Silver nitride

8. Pb₃P₂
- P³⁻ × 2 = -6 → three Pb atoms → each Pb = +4 → Lead(IV) phosphide

9. CaI₂
- Ca²⁺, I⁻ → Calcium iodide

10. K₂SO₃
- SO₃²⁻ is sulfite → Potassium sulfite

11. Fe₂(SO₄)₃
- SO₄²⁻ × 3 = -6 → two Fe → each Fe = +3 → Iron(III) sulfate

12. Cu(C₂H₃O₂)₂
- Acetate ion: C₂H₃O₂⁻ → two of them → Cu²⁺ → Copper(II) acetate

13. AgC₂H₃O₂
- Ag⁺, C₂H₃O₂⁻ → Silver acetate

14. Co₃N₂
- N³⁻ × 2 = -6 → three Co → each Co = +2 → Cobalt(II) nitride
