Find the interionic spacing

Reference no: EM13239631

The cohesive energy of a sodium chloride crystal is 6eV per ion pair. The ionization energy of Na is 5eV and the electron affinity of Cl is 3.75eV. Neglecting the energy of repulsion, estimate the interionic spacing. (The electron affinity of Cl is the binding energy of the last electron of Cl?).
