The larger species between the two given elements is to be determined. Concept introduction: The formation of an ion takes place when an atom loses or gains electrons. When an atom loses electron, the positively charge cations are formed. Its size decreases due to decrease in electron–electron repulsion When an atom gains electron, the negatively charge anions are formed. Its size increases due to increase in electron–electron repulsion. The ionic size tends to increase down the group due to increase in number of shells and decrease along the period because shell remains same and effective nuclear charge increase. In isoelectronic species, the species with the smallest nuclear charge (i.e., the smallest atomic number Z) will have the larger radius. The species with the largest nuclear charge (i.e., the largest atomic number Z) will have the smaller radius.

Solution Summary: The author explains that the larger species between the two given elements is to be determined.
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
Interpretation:
The larger species between the two given elements is to be determined.
Concept introduction:
The formation of an ion takes place when an atom loses or gains electrons.
When an atom loses electron, the positively charge cations are formed. Its size decreases due to decrease in electron–electron repulsion
When an atom gains electron, the negatively charge anions are formed. Its size increases due to increase in electron–electron repulsion.
The ionic size tends to increase down the group due to increase in number of shells and decrease along the period because shell remains same and effective nuclear charge increase.
In isoelectronic species, the species with the smallest nuclear charge (i.e., the smallest atomic number Z) will have the larger radius.
The species with the largest nuclear charge (i.e., the largest atomic number Z) will have the smaller radius.
