Consider sodium chloride (NaCl), which forms a face centered cubic (fcc) crystal lattice. Within this structure, sodium (Na) and chlorine (Cl) ions are positioned such that their separation is defined along half the body diagonal of the cubic unit cell. The atomic numbers of Na and Cl are 11 and 17, respectively.
Identify the X ray diffraction peaks that can be observed from an NaCl crystal. Represent these peaks using Miller indices (hkl) corresponding to a conventional cubic unit cell.
