The increasing order of radius of given pairs have to be arranged and the same has to be explained. Concept introduction: The distance from centre of nucleus to the valence shell electron of an atom or ion is called atomic or ionic radius. Radius of parent atom is always higher than the size of cation. Radius of parent atom is always smaller than the size of anion due to the effective nuclear charge.

Solution Summary: The author explains that the increasing order of radius of given pairs has to be arranged and explained. Radius of parent atom is always higher than the size of cation due to loss of the valence electron.

Which one of the following ions has the smallest radius?
Cl-
K+
S2
Na+
O2
Choose all of the following statements about the bonding atomic radii that are CORRECT?
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.
The large radii of the Group 1A elements are due to their relatively small effective nuclear charges.
For a given period, the radii of the representative elements generally decrease from left to right across a period.
Arrange Sr2+, Li, Br− in decreasing atomic/ionic radius (largest to smallest).
