Which ion forms the weakest ionic bond with a given anion?

A. Cs⁺
B. Li⁺
C. K⁺
D. All of the ionic bonds would be of equal strength.

D. All of the ionic bonds would be of equal strength.

The strength of an ionic bond depends on the charges of the ions involved. In this case, since all the cations (Cs⁺, Li⁺, and K⁺) have a charge of +1, the strength of the ionic bond with a given anion would be the same regardless of the cation.
