Answer

a. $H_{2}S$ is a crystalline molecular solid. b. $KCl$ is an ionic solid. c. $N_{2}$ is a crystalline molecular solid. d. $NI_{3}$ is a crystalline molecular solid.

Work Step by Step

Ionic solids: Solids having formula units as composite units. Atomic solids: These solids have atoms as composite units. Molecular solids: These solids have molecules as composite units. a. $H_{2}S$ is covalently bonded, hence it is crystalline molecular solid. b. $KCl$ is ionic solid as it has two different ions. c. $N_{2}$ is covalently bonded, hence it is crystalline molecular solid. d. $NI_{3}$ is covalently bonded, hence it is crystalline molecular solid.
