(a) Interpretation: The species that is smaller between the pair given is to be predicted. Concept Introduction: Compounds formed up of 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 less number of electrons than the parent atom due to which the force of attraction between protons and electrons increases and due to this, 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 electron increases and the force of attraction between protons and electrons decreases and due to this, size increases.

The species that is smaller between the pair given is to be predicted.
Concept Introduction:
Compounds formed up of 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 less number of electrons than the parent atom due to which the force of attraction between protons and electrons increases and due to this, 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 electron increases and the force of attraction between protons and electrons decreases and due to this, size increases.
