- Metallic Bonding
- Bonds between metals
- Electrostatic attraction between metal ions and delocalised electrons
- Delocalised electron from the outer shell of metal atom
- Bonds between atoms are very strong
- Electrostatic attraction between metal ions and delocalised electrons
- High melting and boiling points
- Lots of energy is needed to break the forces of attraction
- Layers form lattice structure
- Slide over one another
- Malleable
- Ductile
- Slide over one another
- Alloys
- Mixture of a metal and another element
- Disturbs regular arrangement and layers
- Stronger and harder as layers can't slide as easily
- Steel= iron+carbon+nickel
- Brass= Copper+zinc
- Conducts heat and electricity
- Delocalised electrons are free to move and carry charge throughout the structure
- Insoluble in water
- No intermolec. forces
- Iron
- Copper
- Steel
- Aluminium
