[b]1. The equilibrium bond length r_{0} in ion components (or salts) can always be obtained from the tabulated values of cationic, r_{+}, and anionic radii, r_{}, respectively as
r_{0}=r_{+} + r_{} Show how on this basis, and that above (refering to the first part of the problem where i was to verify that the magdelung constants divided by the number of ions in one formula unit is constant(A/v)), the BornLande and BorneMayer equations become the Kapustinskii equations. [b]2. BorneLande equation BorneMayer Equation [b]3. When carrying out the first part of the equation i obtained an average (A/v) value of 0.839 and i can easily derive the actual Borne equations but no matter what i try i cant get a decent answer for the derivation of the Kapustinskii equation Any assistance would be of great appreciation.
