Step 1
First, let's write the possible empirical formulas for binary ionic compounds using the given cations (mg²⁺, au³⁺) and anions (f⁻, o²⁻).
Step 2
For each cation-anion pair, we need to balance the charges. The charge on the magnesium ion is + 2, and the charge on the gold ion is + 3. The charge on the fluoride ion is - 1, and the charge on the oxide ion is - 2.
Final Answer
- MgF₂ - MgO - AuF₃ - AuO₂
