Although all 3 compounds are ionic, the one with the highest ionic characteristics is KCl due to the greater difference between K and Cl than in the other 2.
CsCl would have the most ionic character, since cesium is the most effective electron donor from alkali metals listed in the question.
NaCl KCl MgF2 CaF2 CaCl2 LiCl MgO CaO Na2O K2O
NaCl KCl
SO2 is definitely NOT ionic
NaCl, KCl, MgCl2 etc
Take your pick of ionic compounds? NaCl, NaFl, NaI, NaBr, LiCl, LiFl, LiI, LiBr KI KCl KBr KFl, keep going down group I and II and halogens, and you will have 24 right off the bat.

As the size of Na is smaller than the size of K,NaCl will have stronger bond than KCl
The ionic bonding causes the solubility. As the electronegative difference becomes more, the ions are easily soluble. K has more electronegativity than Na. Hence KCl is more soluble than NaCl in water
ionic: NaCl, KCl, KOH etc covalent: H2, O2, CH4 etc
The non-metal, eg NaCl, MgO, BaO, LiF, KCl.
NaCl - sodium chloride KCl - potassium chloride
kcl...more reactive
KCl is an ionic bond type I
