Metals are amongst the most important materials in society for their useful properties. This chapter looks at the underlying structure of metals and how these properties arise.
A metallic bond is the electrostatic attraction between a lattice of positive ions and delocalized electrons.
The strength of a metallic bond depends on the charge of the ions and the radius of the metal ion.
Alloys usually contain more than one metal and have enhanced properties.
