In an ionically bonded solid the force between two ions is given by where r is the distance between the ions, b and c are constants where b = 1.2x10-28 N·m2 and c = 1.8x10-105 N·m10 . (a) Identify the attractive and repulsive terms in the expression.
(b) Determine the ion separation in Ã… in the solid.
(c) Determine the energy in eV required to separate the ions in the solid to an infinite distance apart.
(d) Sketch E versus r curve for the solid. Label the equilibrium separation and energy minima.
