do u have any idea abt formula to find this ?

anonymous · Answer

E=ze^2/4 pie epsilon r_0(1-1/n)

anonymous · Answer

BE= (Z*e^2/4*pi*epsilon_0*r0)*(1-1/n) its the right formula. be carefully with the exponent

Hello, please I need help what does Z means in this equation I can't find this constant, just that in other Born-Lande equations change to avogadro number and madelung, constant, but this last one is hard to define!! Thank you!!

anonymous · Answer

z its equal to q1*q2 of the potassium and iodine ok
