Metallic Bonding

All metals are solid at room temperature with the exception of mercury. Metals consist of a giant lattice of positive ions surrounded by a shared pool of delocalised electrons.
Metallic bonding is the strong electrostatic attraction between the cations (positive ions) and delocalised electrons.

The delocalised electrons are mobile and can move throughout the structure.
