- metallic bonding
- metals properties are because of the sea of free electrons
- they are delocalised electrons which come from the outer shell of every metal atom in the structure
- delocalised means free
- These electrons are free to move through the whole structure
- This is why metals are good conductors of heat and electricity
- they are delocalised electrons which come from the outer shell of every metal atom in the structure
- metals also consist of a giant structure
- similar to giant covalent
- an example is graphite in a pencil, sliding layers
- This means they have high melting and boiling points
- The electrons hold the atoms together in a regular structure
- Has strong forces of electrostatic attraction
- This means they have high melting and boiling points
- They also allow the layers of atoms to slide over each other
- This allows metals to be bendy and be shaped easily
- metals properties are because of the sea of free electrons
