(a) Interpretation: The species that is larger between the given pair is to be predicted and an explanation for the correct choice is to be stated. Concept Introduction: Compounds formed from ions are known as ionic compounds. The compound consists of the cation and anion. Cation is the positively charged ion and anion is negatively charged ion. Cations are always smaller than the atoms from which they are formed because they have lesser number of electrons than the parent atom due to which the force of attraction between protons and electrons increases size decreases. Anions are always larger than the atoms from which they are formed because they have more number of electrons than the parent atom due to which the repulsion between the electrons increases, the force of attraction between protons and electrons, decreases, and the size increases.

Solution Summary: The author explains that ionic compounds consist of cation and anion. Cations are positively charged and are formed when an atom loses electrons to get stable.
The species that is larger between the given pair is to be predicted and an explanation for the correct choice is to be stated.
Concept Introduction:
Compounds formed from ions are known as ionic compounds. The compound consists of the cation and anion. Cation is the positively charged ion and anion is negatively charged ion.
Cations are always smaller than the atoms from which they are formed because they have lesser number of electrons than the parent atom due to which the force of attraction between protons and electrons increases size decreases.
Anions are always larger than the atoms from which they are formed because they have more number of electrons than the parent atom due to which the repulsion between the electrons increases, the force of attraction between protons and electrons, decreases, and the size increases.
