- Metal atoms are held strongly to each other by metallic bonding.
- In the metal lattice, the atoms lose their valence electrons and become positively charged.
- The valence electrons no longer belong to any metal atom and are said to be delocalised.
- They move freely between the metal ions like a sea of electrons.
Metallic Lattice: Giant three-dimensional lattice structure of positive ions surrounded by a sea of delocalised electrons.
The outer shell of (valence) electrons are detached from the atoms and are delocalised throughout the structure
Metallic Bonding: The attraction between the positive ions and delocalised electrons that keeps the ions together.
Examples of Metallic Compounds:
