Question

HURRY NEED NOW! Calcium has a charge of +2. The chart lists the charges of different ions.

Which are possible equations for an ionic compound with calcium?


CaO, CaMg, or CaF2

Ca2Cl, CaNa, or CaP

CaF, CaMg, or CaNa

CaO, CaF2, or CaCl2

Answer 1

CaO CaF2 CaCl2 are ionic

Step-by-step explanation:

Because electronegativity difference between calcium and other atom is more than 1.7

Answer 2

CaO, CaF2, or CaCl2

Step-by-step explanation:

In an ionic compound, the charges need to balance out. This is the only set of compounds that fits this criteria.
