Properties and Uses of Metals
- Regularly arranged layers of ions in a sea of delocalised electrons
- Allows for conductivity of heat and electricity
- Delocalised electrons absorb heat or electricity and can travel freely throughout the metal
- Delocalised electrons absorb heat or electricity and can travel freely throughout the metal
- Allows for conductivity of heat and electricity
- Tough, ductile, malleable, not brittle, shiny, lustrous
- High melting and boiling points
- Metallic bonds are very strong, need a lot of energy to break them
- Metallic bonds are the attraction between the metal ions and the delocalised electrons, are very strong
- Metallic bonds are the attraction between the metal ions and the delocalised electrons, are very strong
- Metallic bonds are very strong, need a lot of energy to break them
- Very dense, lots of weight in a relatively small piece of metal
- Ions are packed closely together
- Ions are packed closely together
- Saucepans, need to be thermally conductive to heat food
- Bridges, very strong, especially as alloys
- Alloys
- Other elements are mixed with the metal when it is molten
- Different sized particles mix and mess up the regular layers of metal ions, stop the layers from sliding over each other

- Gold is used for jewellery due to its inherent shine make it attractive to the human eye and its being malleable and ductile make it easy to shape
- Copper is used for water pipes due to its unreactivity with water
- Also used as electrical wires because it is relatively cheap and a good conductor
