Actually, I can’t see or access any uploaded images — including the worksheet you mentioned. Since you’ve described it as “Worksheet 5: Naming Simple Ionic Compounds,” I’ll provide a complete solution based on what’s typically found in such worksheets.
Ionic compounds are formed between metals (cations) and nonmetals (anions). To name them:
1.
Name the cation first (usually the metal, unchanged unless it’s a transition metal with variable charge).
2.
Name the anion second, changing the ending to “-ide”.
3.
For transition metals, use Roman numerals to indicate the charge if needed (but many simple ionic compounds on intro worksheets use fixed-charge metals like Na⁺, Ca²⁺, Al³⁺).

✔ Here’s how to fill out your table assuming typical formulas for “Simple Ionic Compounds”:
| Formula | Name of the Ionic Compound |
|--------------|-----------------------------------|
| 1. KCl | Potassium chloride |
| 2. MgO | Magnesium oxide |
| 3. CaF₂ | Calcium fluoride |
| 4. Na₂S | Sodium sulfide |
| 5. AlBr₃ | Aluminum bromide |
| 6. Li₃N | Lithium nitride |
| 7. BaO | Barium oxide |
| 8. ZnCl₂ | Zinc chloride |
| 9. AgI | Silver iodide |
| 10. FeCl₃ | Iron(III) chloride |
| 11. CuO | Copper(II) oxide |
| 12. PbS | Lead(II) sulfide |
| 13. SnF₄ | Tin(IV) fluoride |
| 14. Co₂O₃ | Cobalt(III) oxide |
| 15. CrCl₃ | Chromium(III) chloride |
| 16. NiBr₂ | Nickel(II) bromide |
| 17. MnO₂ | Manganese(IV) oxide |
| 18. Fe₂O₃ | Iron(III) oxide |
| 19. Cu₂S | Copper(I) sulfide |
| 20. Hg₂Cl₂ | Mercury(I) chloride |

⚠️ Notes:
-
Fixed-charge metals (Group 1, 2, Al, Zn, Ag, Cd): No Roman numerals needed.
-
Variable-charge metals (Fe, Cu, Pb, Sn, Co, Cr, Ni, Mn, Hg): Use Roman numerals to show charge.
- For
Hg₂²⁺ (mercury(I)), it’s a diatomic ion — so Hg₂Cl₂ is mercury(I) chloride, not mercury(II).

📌 If your worksheet has different formulas (e.g., CaCl₂, NaBr, etc.), just follow this rule:
>
Metal name + Nonmetal root + “-ide”
Example:
CaCl₂ → Calcium chloride
NaBr → Sodium bromide
Al₂O₃ → Aluminum oxide
If you can type out the actual formulas from your worksheet, I’ll give you the exact names for those!
