Calcium (Ca) and Chlorine (Cl). in CaCl2

Column B
a.The electronegativity difference is 1. The bond will be polar covalent.
b.The electronegativity difference is 0. The bond will be nonpolar covalent.
c.The electronegativity difference is 1. The bond will be nonpolar covalent.
d.The electronegativity difference is 2.0. The bond will be ionic.
e.The electronegativity difference is 0. The bond will be ionic.
f.The electronegativity difference is 2.0. The bond will be polar covalent.
