Step 1
For the ionic compound formed between Mg²+ and S²-, the empirical formula is MgS. This is because magnesium always loses two electrons to form an Mg²+ ion, and sulfur always gains two electrons to form an S²- ion. Therefore, one magnesium ion will combine with one sulfur ion to form an electrically neutral compound.
Step 2: Write the charges of the ions
Mg^{2+} \text{ and } S^{2-}
Final Answer
The names and empirical formulas of the ionic compounds are: 1. MgS 2. Mg₃N₂ 3. Mg₃P₂ 4. MgO
