Textbook Question

Chapter 7, Problem 36E

In the ionic compoundsLiF,NaCI,KBr, andRbl, the measured cation-anion distances are 2.01 A (Li-F), 2.82 A (Na-CI), 3.30 A (K-Br), and 3.67 A (Rb-I), respectively. (a) Predict the cation-anion distance using the values of ionic radii given in Figure 7.8 (b) Calculate the difference between the experimentally measured ion-ion distances and the ones predicted from Figure 7.8. (c) What estimates of the cation-anion distance would you obtain for these four compounds using neutral atom bonding atomic radii? Are these estimates as accurate as the estimates using ionic radii?
