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?).

Successive ionization energies are not
represented in the experimental photoelectron spectra. It’s
important to realize that PES simply shows the energies required to
photoionize ONE electron from a neutral atom. In the case of the
nitrogen PES spectrum you examined in section, the one electron
photoionized can be from the 1s, 2s or 2p subshell in its ground
state.
In contrast, successive
ionization energies correspond to the removal of
more than one electron from a given atom. These
electrons are...

The minimum energy needed to eject an electron from an atom is called its ionization energy I. In atomic physics, I is usually measured in electron-Volts (eV), with 1 eV being the energy needed to move a charge of 1 e across an electrostatic potential difference of 1 V, 1 eV = 1.602 x 10-19 CX1V -1.602 x 10-19 J. For the hydrogen atom | = 13.60 eV. If a photon ejects an electron with kinetic energy 5.0 eV from...
