A giant metallic structure is a group of metal atoms held together by metallic bonds.

In giant metallic structure the metal atoms are held together as a lattice of positive ions surrounded by a sea of delocalised electrons.

In a pure element the atoms are arranged in a regular lattice.

When there is a mixture of metal elements it is called an alloy and the different atoms change the pattern in the lattice.

A small number of different metal atoms added to a material can change the physical properties and chemical properties of the material.

Property	Reason
Malleable and ductile	The delocalised electrons are free to move so when the metal ions slide past each other the metallic bonds remain just as strong and the material doesn't break.
Good Electrical Conductor	The delocalised electrons are free to move in an electrical current.
Good Thermal Conductor	The delocalised electrons are free to move through the metal carrying thermal energy through the material.
High Melting Point	There is a strong electrostatic force between the positive ions and the delocalised electrons.
