Model of the cubic crystal lattice of sodium chloride (pure common salt). The cubic crystal consists of an ionic lattice of Sodium (Na+) and Chlorine (Cl-) ions,where the repeating units of the lattice are positively & negatively charged respectively. Sodium ions are represented by red spheres,chlorine ions as green spheres. Ionic crystals tend to be hard & brittle,due to the strong electrostatic forces between the constitutent ions | |
