Why do samples of ionic compounds break into pieces, but the pieces do not combine into larger samples again?

A distinct property of ionic compounds is that they are brittle. We are taught this is due to the fact that when force is applied to the lattice, ions are shifted, resulting in positive ions repelling ...

Does an ionic bond have a dipole?

Is an ionic compound like NaCl considered a dipole? It has a positive side (Na+) and a negative side (Cl-). Or is it true that an ionic bond does not have a dipole because a dipole is, by definition, ...
