4.2.1.5 Metallic bonding

Content

  • Metals consist of giant structures of atoms arranged in a regular pattern.
  1. The electrons in the outer shell of metal atoms are delocalised and
  2. so are free to move through the whole structure. The sharing of delocalised electrons gives rise to strong metallic bonds. The bonding in metals may be represented in the following form:
