SUMMARY
The discussion focuses on the face-centered cubic (FCC) structure of sodium chloride (NaCl), specifically calculating the separation between nearest neighbors, sodium (Na) and chlorine (Cl). The lattice parameter is given as a = 5.63 angstroms. The separation is derived from the FCC geometry, where the nearest neighbor distance is calculated as a/2, but the correct interpretation involves understanding the positions of the atoms in the unit cell, leading to a distance of a/sqrt(2).
