### Determining Empirical Formulas of Binary Ionic Compounds

**Problem Statement:**
Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions:

- \(\text{Mg}^{2+}\)
- \(\text{Fe}^{2+}\)
- \(\text{Cl}^{-}\)
- \(\text{S}^{2-}\)

**Ions List:**
1. Magnesium ion: \(\text{Mg}^{2+}\)
2. Iron(II) ion: \(\text{Fe}^{2+}\)
3. Chloride ion: \(\text{Cl}^{-}\)
4. Sulfide ion: \(\text{S}^{2-}\)

**Example Binary Ionic Compounds:**
To form neutral ionic compounds, the total positive and negative charges must balance out. Here are at least four examples:

1. **Magnesium Chloride:**
   - Formula: \(\text{MgCl}_2\)
   - Magnesium ion (\(\text{Mg}^{2+}\)) combines with two Chloride ions (\(\text{Cl}^{-}\)) to form a neutral compound.

2. **Magnesium Sulfide:**
   - Formula: \(\text{MgS}\)
   - Magnesium ion (\(\text{Mg}^{2+}\)) combines with one Sulfide ion (\(\text{S}^{2-}\)) to form a neutral compound.

3. **Iron(II) Chloride:**
   - Formula: \(\text{FeCl}_2\)
   - Iron(II) ion (\(\text{Fe}^{2+}\)) combines with two Chloride ions (\(\text{Cl}^{-}\)) to form a neutral compound.

4. **Iron(II) Sulfide:**
   - Formula: \(\text{FeS}\)
   - Iron(II) ion (\(\text{Fe}^{2+}\)) combines with one Sulfide ion (\(\text{S}^{2-}\)) to form a neutral compound.
