(a) Interpretation: To arrange the given set of species in order of their increasing radius. Rb, K, Cs and Kr Concept introduction: The Modern Periodic law states that the physical and chemical properties of the elements are a periodic function of their atomic numbers . This means that changes in the chemical properties of various elements present in the modern periodic table are due to their atomic numbers. Atomic number of elements gives the total number of electrons or protons present in that atom. The main cause of periodicity is the repetition of similar outer electronic configuration after regular intervals.

Solution Summary: The author explains that the physical and chemical properties of various elements present in the modern periodic table are a periodic function of their atomic numbers.
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:
To arrange the given set of species in order of their increasing radius.
Rb, K, Cs and Kr
Concept introduction:
The Modern Periodic law states that the physical and chemical properties of the elements are a periodic function of their atomic numbers. This means that changes in the chemical properties of various elements present in the modern periodic table are due to their atomic numbers. Atomic number of elements gives the total number of electrons or protons present in that atom. The main cause of periodicity is the repetition of similar outer electronic configuration after regular intervals.
Interpretation Introduction
(b)
Interpretation:
To arrange the given set of species in order of their increasing radius.
Ar, Si, Al, Cs
Concept introduction:
The Modern Periodic law states that the physical and chemical properties of the elements are a periodic function of their atomic numbers. This means that changes in the chemical properties of various elements present in the modern periodic table are due to their atomic numbers. Atomic number of elements gives the total number of electrons or protons present in that atom. The main cause of periodicity is the repetition of similar outer electronic configuration after regular intervals.
