Crystal structure of ionic compound
WebAug 14, 2024 · Structurally, each ion in sodium chloride is surrounded and held in tension by six neighboring ions of opposite charge. The resulting … WebThe energy required to separate the ions in a crystal lattice into individual gaseous ions is known as lattice energy. Lattice energy depends on the strength of interactions between cations and anions in the lattice, which we can estimate using Coulomb's law: Fₑ = (q₁q₂)/r².According to this equation, stronger interactions occur between ions with larger …
