Question: is cacl2 polar or nonpolar?
Answer: Chlorine has a value of 3.0 and Calcium a value of 1.0. Subtract and find the absolute value, and you get 2.0. The scale you use is 1.8-2.9 is an ionic bond, 0.5-1.8 is polar covalent, and 0.0-0.4 is nonpolar covalent. So in that regard, CaCl2 is ionic.
