You may want to reference (Pages 263 - 267) Section 7.3 while completing this problem.

Which of the following statements about the bonding atomic radii in the following figure is incorrect?

A periodic table shows that radius increases moving down the columns and left across the rows. Of those shown, Rubidium has the largest radius, and Helium has the smallest.
(i) For a given period, the radii of the representative elements generally decrease from left to right across a period.
(ii) The radii of the representative elements for the n = 3 period are all larger than those of the corresponding elements in the n = 2 period.
(iii) For most of the representative elements, the change in radius from the n = 2 to the n = 3 period is greater than the change in radius from n = 3 to n = 4.
(iv) The radii of the transition elements generally increase moving from left to right within a period.
(v) The large radii of the Group 1A elements are due to their relatively small effective nuclear charges
