Metallic Bonding

Metallic bonds are the electrostatic attractions between positive ions and negative delocalised electrons.

Positive ions

Positive ions

Metals are made of giant structures of regularly arranged atoms.
The structure is a regular lattice of positive ions (cations) in a ‘sea’ of delocalised electrons.

Delocalised electrons

Delocalised electrons

Delocalised electrons are not bound to an atom and are free to move around within the lattice.
Delocalisation happens because metal atoms have a small number of electrons in their outer shells.
