TestHub · Accepted Answer

Ionic solids are formed by the electrostatic attraction between cations and anions. $K_{2} SO_{4}$ is an ionic solid composed of $K^{+}$ and $SO_{4}^{2 -}$ ions.

Covalent or network solids consist of atoms held together by a continuous network of covalent bonds. Quartz ( $SiO_{2}$ ) is a classic example of a covalent solid.

Molecular solids are composed of discrete molecules held together by intermolecular forces. Solid $CO_{2}$ (dry ice) is a molecular solid held together by London dispersion forces.

Metallic solids consist of a lattice of positive metal ions in a sea of delocalized electrons. Potassium ( $K$ ) is a metallic solid.

Thus, the correct matching is (A) - (II), (B) - (IV), (C) - (I), (D) - (III).

Answer: (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
