What geometry shape is formed by sodium and chlorine?

The geometry shape formed by sodium (Na) and chlorine (Cl) in sodium chloride (NaCl) is a cubic lattice structure. In this ionic compound, sodium ions (Na⁺) and chloride ions (Cl⁻) arrange themselves in a regular, repeating three-dimensional pattern, resulting in a face-centered cubic (FCC) arrangement. This structure maximizes the electrostatic attraction between the oppositely charged ions while minimizing repulsion.
