- metallic bonding
- this is a regular lattice structure o= positive ions and - = sea of delocalised electrons.
- Metallic Bond: The attraction of positive ions to delocalised electrons.
- Properties
- strong and dense
- Conducts electricity and heat
- malleable
- Shiny when cut
- Can be drawn out into wires
- High melting and boiling point
- METALS conduct electrcity because they can carry the charge as the delocalised electrons are free to move.
- Metals have very high melting and boiling point so large amounts of energy are needed to break down the strong attraction between positive ions and the delocalised electrons.
- WHEN ANSWERING QUESTIONS LOOK AT THE DELOCALISED ELECTRONS AND THE MORE DELOCALISED ELECTRONS THE STRONGER IT IS FOR THE BOND TO BREAK
