A 3D construction model shows how the ions are arranged in a lattice structure. These models usually use coloured balls to represent the ions. Some use sticks to show the ionic bonds. A 3D ...

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) of ionic hard spheres. The cohesive energy of NaCl is - ...

The three states of matter can be represented by the particle model ... compounds - AQA An ionic compound is made up of charged particles, called ions. It has a giant lattice structure with ...
