Metallic Bonding

Metallic bonding holds together solic metals. This includes metal elements, such as iron and copper, as well as alloys like steel and brass.

Positive ions are fixed, whilst outer-shell electrons are delocalised and are shared between atoms of metal.

Giant Metallic Lattices

Metal elements exist as giant metallic lattices.

Properties of giant metallic lattices:

  • The more delocalised electrons, the higher the melting point (because more electrons give the structure more strength)
  • Metals are malleable and ductile--they can be shaped by hammer or by drawing them out
  • They are good conductors of heat and electricity


However, these properties can be altered by mixing metals into alloys. For example, steel, a mixture of iron and carbon, is stronger than iron alone.
