For NaCl, the ionic radii for Na+ and Cl ions are 0.102 and 0.181 nm, respectively. If an externally applied electric field produces a 5% expansion of the lattice, compute the dipole moment for each Na+-Cl- pair. Assume that this material is completely unpolarized in the absence of an electric field.
