To match the correct formula to its ionic compound, we need to understand how to derive the formulas from the names of the compounds. Here's a breakdown of the ionic compounds mentioned in the question:

1. Sodium Sulfide: Sodium (Na) has a +1 charge, and sulfide (S) has a -2 charge. To balance the charges, we need two sodium ions for each sulfide ion. Thus, the formula is: $\text{Na}_2\text{S}$

2. Caesium Oxide: Caesium (Cs) has a +1 charge, and oxide (O) has a -2 charge. Similarly, we need two caesium ions for each oxide ion to balance the charges. Hence, the formula is: $\text{Cs}_2\text{O}$

Based on these analyses, the correct matches are:

• Sodium Sulfide corresponds to $\text{Na}_2\text{S}$.
• Caesium Oxide corresponds to $\text{Cs}_2\text{O}$.

Final Answer

• Sodium sulfide: $\text{Na}_2\text{S}$
• Caesium oxide: $\text{Cs}_2\text{O}$
