Ionic crystal(a) Determine the Madelung constant for NaCl including only the nearest neighbors and the next nearest neighbors in the sum. (b) The cohesive energy of NaCl can be described by the function, Here R is the interatomic spacing and z is the number of nearest neighbors. λ,ρ and α are constants. How could you determine the density of NaCl from this expression? |
