Key Questions:

1. What is the structure of a metal like?
   • Metals consist of giant structures of atoms arranged in a regular pattern.
2. How are the electrons in the outer shell of metal atoms arranged?
   • The electrons in the outer shell of metal atoms are delocalised and so are free to move through the whole structure.
3. Why are metallic bonds so strong?
   • The sharing of delocalised electrons gives rise to strong metallic bonds. The bonding in metals may be represented in the following form: (diagram)
4. Describe the structure of metallic bonding?
   • positive atoms surrounded by negatively charged delocalised electrons
5. When compared with the properties of materials, do atoms have the same bulk properties?
   • Atoms themselves do not have the bulk properties of materials.
