Yes, any combination of a metal and a nonmetal could potentially form am ionic compound. However, some reactions may have to be forced by raising temperature, changing pressure, or stressing equilibrium. In this particular case, though, they would react to make CaCl2 or calcium chloride.
cesium fluoride
Yes, the elements potassium and chlorine will react--very vigorously--to form the ionic compound potassium chloride.
Chlorine
Sulfur can form ionic compounds (eg SO2), but Xenon is a noble gas and does not react to form compounds.
Ionic compounds are formed between metals and non-metals.
sodium
cesium fluoride
Yes, the elements potassium and chlorine will react--very vigorously--to form the ionic compound potassium chloride.
Zinc and chlorine react to form the binary ionic compound zinc chloride, which has the formula ZnCl2.

Ionic compounds are formed between metals and non-metals.
An ionic compound can form interactions with water. Water happens to be a polar molecule. The positive ions are going to react with the partially charged negative ions (that are in the water). The negative ions will react with the partially positive charged hydrogen atoms in the water. But the ionic compound won't dissolve in oil because it can't form the same reaction.
They will form a covalent compound.
Lithium and fluorine react together to form lithium fluoride which is an ionic compound.

Calcium would form Ca2+ and chlorine would form Cl-. The ionic compound would be CaCl2 to ensure a neutral charge for the whole compound.
