Basic model for solids

  1. Jan 14, 2013 #1
    Given two ionic cores, i and j, can someone please explain what it is that's happening as the distance between them decreases? What is its significance?

    It is difficult to know what exactly you are asking here. Are you asking why, as the two ions gets closer, the field changes? Isn't this just a standard E&M problem?

    Or are you asking what would cause the two ions to be closer?

    All I can see is that they are forming bonding orbitals from non-bonding orbitals. But that itself does not make any solid.

    For chemists easy explanation see in a book
