Question

For a crystal of sodium chloride, state the structural arrangement of the sodium chloride crystal.

Answer 1

For a crystal of sodium chloride, the structural arrangement consists of chloride ions (Cl⁻) forming a face-centred cubic (FCC) lattice, with sodium ions (Na⁺) occupying the octahedral voids. This results in a three-dimensional, alternating arrangement of Na⁺ and Cl⁻ ions, where each ion is octahedrally surrounded by six oppositely charged ions.
