Homework Answers
Ionization energy of Cl- ion is the energy required to remove an electron from the outermost orbit of the isolated gaseous atom and electron affinity of Cl is energy released when an electron is added to the neutral chlorine atom. So
Electron affinity of Cl= Ionization energy of Cl-.
They are different in the sense that for Ionization energy it is energy released and for electron affinity it is energy absorbed.

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?).

How does the ionization energy of the singly charged anion I− relate to the electron affinity of the neutral atom? A) The ionization energy of I− and the electron affinity of I are not related. B) The ionization energy of I− is half the electron affinity of I because the reaction is more favorable. C) The ionization energy of I− is the same magnitude as the electron affinity of I, but has the opposite sign. D) The ionization energy of...

The total potential energy describing the NaCl lattice is given by: Utot = [ ( -(αe^2) / (4πε 0r) ) + ( A / r^8 ) ], where a is the Madelung constant (a=1.75 for NaCl) and A is a positive constant. 1. What is the physical meaning of the two terms of Utot? Let r0 be the value of the ionic separation r for which Utot is minimum. 2. Deduce an expression of A as a function of r0....
