THE most direct way by which an ion can be displaced in an ionic lattice when the lattice is subjected to ionizing radiation is through simple collision displacements. Thus high-energy electrons ...

The lattice arrangement continues in three dimensions. This is why solid ionic compounds form crystals with regular shapes.

The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit cell with ion locations indicated (a) and a space filling model (b ...
