Bonding

Metallic Bonding

• Positive ions surrounded by a 'sea' of delocalised electrons.
• Strong attraction between ions and delocalised electrons.
• High melting points, almost all are solids at room temp.
• Conduct heat.
• Conduct electricity.
• Malleable.
• Sodium.

Giant Ionic Structure

• Regular 3D arrangement of positive and negative ions.
• Strong electrostatic attraction between positive and negative ions.
• High melting points,…
