Final answer:

Ionic bonds involve the transfer of electrons between ions of opposite charges, creating a bond not specific to individual ions. Calcium chloride is primarily ionic as it contains cations and anions held together by ionic bonds.


Explanation:

Ionic bonds are formed between atoms by the transfer of electrons from a metal to a nonmetal, resulting in the formation of cations and anions that are held together by electrostatic forces. This creates a bond between ions of opposite charges.

Unlike covalent bonds, ionic bonds are not specific to one particular cation and anion. In an ionic compound, there is a lattice structure where cations and anions are arranged in a repeating pattern rather than being between specific ions.

For example, calcium chloride, CaCl2, is primarily ionic because it consists of Ca²+ cations and Cl- anions held together by ionic bonds due to the transfer of electrons from calcium to chlorine.
