Figure 1 shows a fragment of the sodium chloride crystal structure: grey ions represent sodium, and green chloride; the ions are only shown at half-radius size to show the structure more clearly; blue lines connect ions that are, in reality, touching. This fragment is known as a unit cell because the bulk crystal structure can be obtained by ...

Figure 2 illustrates the space lattice and the unit cell for a real three-dimensional crystal structure—that of sodium chloride. This is the same structure that was shown for lithium hydride, except that the sizes of the ions are different. A unit cell for this structure is a cube whose comers are all occupied by sodium ions.

Figure 4.3. Formation of ionic sodium chloride from neutral Na and Cl atoms. Sodium chloride is a very stable compound because of the mutual attraction of oppositely charged ions. But the ions have to be arranged in an optimum manner for this attraction to be effective. Since oppositely charged ions attract each other, but ions with …

Sodium chloride (NaCl) dissolves when water molecules continuously attack the NaCl crystal, pulling away the individual sodium (Na +) and chloride (Cl –) ions. This nonstop attack continuous until the whole NaCl crystal disintegrates. To understand this process at the molecular level, we must apply the three steps we previously discussed.

When a crystal of sodium chloride is placed into water, the water's molecules collide with the crystal lattice. Recall that the crystal lattice is composed of alternating positive and negative ions. Water is attracted to the sodium chloride crystal because water is polar and has both a positive and a negative end. The positively charged sodium ...

A sodium chloride crystal has an equilibrium separation of 0.282 nm. (Compare this value with 0.236 nm for a free diatomic unit of NaCl.) The dissociation energy depends on the separation distance, repulsion constant, and Madelung constant for an FCC structure. The separation distance depends in turn on the molar mass and measured density.
