(a) Interpretation: Whether Rb or Rb + is larger should be determined. Concept introduction: Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.

Solution Summary: The author explains that if Rb is larger, it should be determined. Atomic radius is the distance between the valence shell and atomic nucleus.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

Interpretation Introduction
(a)
Interpretation:
Whether Rb or Rb+ is larger should be determined.
Concept introduction:
Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.
Interpretation Introduction
(b)
Interpretation:
Whether N or N3− is larger should be determined.
Concept introduction:
Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.
Interpretation Introduction
(c)
Interpretation:
Whether Cr3+ or Cr6+ is larger should be determined.
Concept introduction:
Atomic radius is the distance between the valence shell and the atomic nucleus. Down the group, more shells are added in successive members and the atomic radius increases. It decreases in the period as an effective nuclear charge increases.
