Sodium chloride - Wikipedia
This same basic structure is found in many other compounds and is commonly known as the NaCl structure or rock salt crystal structure. It can be represented as a face-centered cubic (fcc) lattice with a two-atom basis or as two interpenetrating face centered cubic lattices. The first atom is located at each lattice point, and the second atom is ...

Lattices and Unit Cells of Salt - Chemistry LibreTexts
2023年3月10日 · Crystal Lattice and Unit Cell of Salt. The regular three-dimensional arrangement of atoms or ions in a crystal is usually described in terms of a space lattice and a unit cell. Salt occurs in this structure as well. The formula of salt is NaCl, made up of sodium and chlorine ions. These two ions come together to form the lattice.
What Are Salt Crystals, and How Are They Formed?
Salt crystals are solid, three-dimensional structures that form when dissolved salt, typically sodium chloride (NaCl), solidifies. These crystals are made up of repeating patterns of sodium (Na⁺) and chloride (Cl⁻) ions arranged in a regular, orderly lattice structure.
