Metallic Bonding (C4)

Properties of metals:

• Conducts electricity
• Shiny
• Strength
• Heat conductor
• Malleable - can be hammered/shaped without breaking 
• Ductile - can be drawn out into a thin wire
• Sonarous - makes a noise when dropped
• High melting/boiling point

You have to be able to look at a use of metal and link it to the property of a metal. eg. Aluminium for saucepans because it conducts heat

Metals have metal ions surrounded by a sea of electrons. These decolourised electrons are free to move through the metal. The negative electrons glue the positive ions together. 

Metals are good conductors of electricity because the decolourised electrons already move around the metal randomly and when we give an electric charge to…
