[nodyl]

This week at school we did the Born-Mayer equation:

V=(N_A^z_A^z_B^e2)/(4??₀d) x (1-d^*/d) x A

I know that v is the coulomic potential energy, A is the madelung constant, that N_A is the number of ions per formula unit, _z^A and _z^B represent the charge number of the ions, d is the distance between an anion and a cation, d^* is a constant (taken as 0.345 angstrom).

The problem that I found in understanding this equation is the significance of each component in the above equation. Can someone very briefly explain their significance.

I hope that this thread doesn't require any attempt to the question I asked.
