Which of the following statements about the bonding atomicradii in Figure 7.7 is incorrect? (i) For a given period, the radiiof the representative elements generally decrease from leftto right across a period. (ii) The radii of the representativeelements for the n = 3 period are all larger than those of thecorresponding elements in the n = 2 period. (iii) For mostof the representative elements, the change in radius from then = 2 to the n = 3 period is greater than the change in radiusfrom n = 3 to n = 4. (iv) The radii of the transition elementsgenerally increase moving from left to right within a period.(v) The large radii of the Group 1A elements are due to theirrelatively small effective nuclear charges.

Question
Which of the following statements about the bonding atomic
radii in Figure 7.7 is incorrect? (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.
