What bonding operates in #Na^+Cl^-#?

Now of course, in the extended array, there is ELECTROSTATIC REPULSION between cations in adjacent formula units...and of course between anions. But if you sum up ALL the attractive interactions between gegenions, and ALL of the repulsive interactions between ions of like charge (and certainly this may be done quantitatively) a net ATTRACTIVE force results that binds the ionic lattice together.
