Question

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

1. The large radii of the Group 1A elements are due to their relatively small effective nuclear charges.

2.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.

3.The radii of the transition elements generally increase moving from left to right within a period.

4.For a given period, the radii of the representative elements generally decrease from left to right across period.

5.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.

Explanation / Answer

The radii of the transition elements generally increase moving from left to right within a period.(incorrect)

Explanation:

effective nuclear charge increases when we move from left to right so radii of elements decreases.
