Brief Explanations:

1. For (K_2O): Potassium is (K^+) and oxygen is (O^{2 -}), so it's potassium oxide.
2. For (SrCl_2): Strontium is (Sr^{2+}) and chlorine is (Cl^-), so it's strontium chloride.
3. For (Al_2O_3): Aluminum is (Al^{3+}) and oxygen is (O^{2 -}), so it's aluminum oxide.
4. For (LiBr): Lithium is (Li^+) and bromine is (Br^-), so it's lithium bromide.
5. For (CaS): Calcium is (Ca^{2+}) and sulfur is (S^{2 -}), so it's calcium sulfide.

Answer:

1. Potassium oxide
2. Strontium chloride
3. Aluminum oxide
4. Lithium bromide
5. Calcium sulfide
