The crystal structure of sodium chloride is face centred cubic if the minimum separation between the na and Cl minus ion is R then assuming the lattice only up to the to nearest neighbouring ions the madelung constant will be
Hi,
The crystal structure of sodium chloride (NaCI) is face centered cubic. If the minimum separation between the Na* and Cl- ion is 'r', then assuming the lattice only upto the two nearest neighbouring ions, the Madelung constant will be --- 0.8665 O-1.7476 .
Hope this helps.
Good luck.
