Which of the following characteristics must be present in any particulate-level model of a crystalline ionic solid that is consistent with Coulomb’s law?
(a) Random placement of ions provided the overall charge is zero
(b) A regular, repeating alternation of cations and anions throughout three dimensions
(c) Like-charged ions occupying nearest-neighbor lattice sites to balance repulsive forces
(d) Variable ion–ion distances within a single unit cell so that larger ions are farther apart
