The correct formula unit for aluminum sulfide is made up of 2 aluminum ions (Al³⁺) and 3 sulfide ions (S²⁻) to balance the charges. Therefore, the formula unit is:
\[
\text{Al}_2\text{S}_3
\]
This means the answer is:
- 2 Al³⁺ ions and 3 S²⁻ ions.
\[
\text{Al}_2\text{S}_3
\]
This means the answer is:
- 2 Al³⁺ ions and 3 S²⁻ ions.
