Question
The interaction energy between Na+ and Clions in the NaCl crystal can be written as () = [(. / ) + ( . / )
The interaction energy between Na+ and Clions in the NaCl crystal can be written as () = [(. / ) + ( . / ) ] Where the energy is given in joules per ion pair and the interionic separation r is in metres
i. Calculate the binding energy and equilibrium separation between Na+ and Clions .
ii. Also estimate the elastic modulus Y of NaCl given that; Y = (1/6r0) [ d2E/dr2 ] r=r0
