Visualizing ConceptsIllustrated are four ions — A, B, X,

Chapter , Problem 2E

(choose chapter or problem)

Illustrated are four ions \(-A, B, X \text { and } Y-\) showing their relative ionic radii. The ions shown in red carry positive charges: a \(2+\) charge for A and a \(1+\) charge for B. Ions shown in blue carry negative charges: a 1- charge for X and a 2- charge for Y.

(a) Which combinations of these ions produce ionic compounds where there is a \(1: 1\) ratio of cations and anions?

(b) Among the combinations in part (a), which leads to the ionic compound having the largest lattice energy? [Section 8.2]
