Polyhedral Models

Introduction to Polyhedral Models     An alternative to represent ionic compounds is to use polyhedral models. When we can see the way in which three=dimensional shapes represent the individual units, it helps visualize long range order. The crystal structure model becomes unwieldy when you represent long range order in the form of multiples of […]

Solid Voids

  To grasp the structure of metals and ionic compounds, you must account for the solid voids. As atoms occupy lattice points, they create a pattern of empty spaces between atoms.     Empty space resides within an extended array of atoms or ions. The character of solid voids produces the properties of alloys, the […]
