  • Structure of an ionic lattice- Sodium chloride
    • Consists of sodium ions each surrounded by six chloride ions.
      • In turn, each Cl- ion is surrounded by siix Na+ ions.
    • The ions are held together by attractions between these oppositely charged ions.
      • This allows an ionic lattice to be built up.
    • Similar electrostatic bonds hold all ionic lattices together.
    • The lattice structure of sodium chloride is said to be simple cubic.
    • Sometimes, ionic crystals contain some water molecules.
      • These water molecules sit within the ionic lattice and are known as water of crystalisation.
      • These crystals are said to be hydrated.
