Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.

In the crystal structure of CsCl (cesium chloride), Cs + ions form the base of a cube while a Cl− ion occupies its center (see Figure 1). Each edge of the cube measures 0.4 nm. Each electron lacks Cs + ions (therefore, the charge of each is + e), while the Cl− ion has one in excess (therefore its charge is -e). (a) What is the magnitude of the resulting electrostatic force exerted by the eight Cs + on the Cl− ion? (b) If one of the Cs + ions is missing, the crystal is said to be imperfect. What is the magnitude of the resulting electrostatic force that the seven Cs + ions then exert on the Cl− ion?

• Density: In both solids and liquids, the molecules are held very closely together and therefore their densities are about the same. In gases, there is space between the molecules. • Molecular movement and order: The molecules in solids are arranged in a regular pattern that does not allow for diffusion, although does allow for vibrations. The arrangement of molecules in a liquid, although not completely random, is not completely fixed. Molecules in a gas are randomly arranged and move very quickly. Gases diffuse quickly in comparison to liquids. Compressibility and thermal expansion: Since the molecules in solids and liquids are already very close together, applying pressure does not greatly affect the volume. In contrast, the space between gas molecules allows for a great deal of compressibility. Although temperature changes will cause slight variations in the volume of a solid or liquid, those variations are negligible compared to the thermal expansion of a gas. Shape and…
