Dear student,

The Madelung constant is used in determining the electrostatic potential of a single ion in a crystal by approximating the ions by point charges. It is named after Erwin Madelung, a German physicist.

If we talk of an infinite line of alternating ions, then just thought it of a one dimensional array. And its value comes out to be 2ln2.

Hope this helps.
