Structure of Ionic Solids Practice Test

The solid contains alternating neutral $\mathrm{CaF}$ units that pack together without electrostatic attraction.

The solid is an amorphous network in which ions are randomly distributed with no repeating pattern.

Each $\mathrm{Ca}^{2+}$ is surrounded by $\mathrm{F}^-$ ions, and each $\mathrm{F}^-$ is surrounded by $\mathrm{Ca}^{2+}$ ions in a 3D array.

The solid is a metallic lattice in which $\mathrm{F}^-$ ions contribute delocalized electrons.

The solid consists of discrete $\mathrm{CaF_2}$ molecules held together by intermolecular forces.
