Metals have a crystalline structure where the atoms are packed closely together. Metallic bonding occurs when metal atoms contribute electrons to a shared "sea of electrons" that can move freely throughout the metal structure. This leaves the metal atoms with a positive charge that attracts them to the negative sea of delocalized electrons, allowing metals to conduct electricity and change shape under force.

- 2. • In a metal crystal the atoms are packed as close together as possible. • This is a giant structure.
- 3. • Metallic bonding is strong bonding. • Each metal atom contributes one or two electrons to a shared ‘sea’ of electrons. • The shared bonding electrons can move through the whole metal structure.
- 4. Metallic Bonding • The outer electrons are allowed to move throughout the metallic structure to form a ‘sea of electrons’ • The metal atoms are left with a positive charge and are attracted to the negative ‘sea
- 5. You need to be able to represent the bonding in a metal like this… Copy and annotate this diagram
