Part 1: Naming the Ionic Compounds

#### Given Formulas:
1. Al₂O₃
2. CuCl₂
3. Mg(NO₃)₂
4. Ca₃N₂
5. SrBr₂
6. Cs₂S
7. Al₂S₃
8. LiBr
9. Mg₃(PO₄)₂
10. CoF₂

#### Solution:
To name ionic compounds, we follow these rules:
- The cation (positive ion) is named first.
- The anion (negative ion) is named second.
- For transition metals with variable charges, Roman numerals are used to specify the charge.
- Polyatomic ions have specific names that must be memorized.

##### Naming Each Compound:
