How is the structure of a NaCl lattice determined and what properties does it exhibit?

The structure of a NaCl lattice is determined by the arrangement of sodium (Na) and chloride (Cl) ions in a repeating pattern. This pattern is based on the strong electrostatic attraction between the positively charged sodium ions and the negatively charged chloride ions. The NaCl lattice exhibits properties such as high melting and boiling points, hardness, and electrical conductivity when dissolved in water.
