Arrange the following elements in order of decreasing atomic radius: Sc, Rb, S, P, Ge, F.

Rank elements from largest to smallest

In the ionic compounds LiF, NaCl, KBr, and RbI, the measured cationâanion distances are 2.01 AÌ (LiâF), 2.82 AÌ (Na-Cl), 3.30 AÌ (KâBr), and 3.67 AÌ (RbâI), respectively.

Predict the cation-anion distance of each ionic compound above using the values of ionic radii given in Figure 7.7 on page 257 in the textbook. To receive full credit, you must show how you predicted the distance for each molecule by providing a step-by-step solution for each molecule. The solution for each molecule is worth 8 points; thus, a total of 32 total points is possible for this question.
