Ionic structures . . .
Takes NaCl as a typical example to show the relationship between the physical properties of an ionic compound and its structure. Also compares the structures of NaCl and CsCl.
Giant covalent structures . . .
Looks at diamond, graphite and silicon dioxide and the way their physical properties are affected by their structures.
Metallic structures . . .
Looks at the relationship between the physical properties of metals and their structures.
Molecular structures . . .
Looks in detail at the structures of ice, iodine and poly(ethene) as well as dealing in general with the sort of physical properties you might expect of molecular substances.
How to decide . . .
Explains how you can decide which sort of structure a substance has by looking at its physical properties.
Physical properties of Period 3 elements . . .
Explains how the structures of the elements from Na to Ar in the Periodic Table affect their simple physical properties.
