- Bonding and structure
- Ionic bond (Between metals and non metals
- A giant structure
- Melting point is usually high as it needs more energy to overcome the bonds.
- Does not conduct electricity when solid but will do when molten or dissolved in water as the ions are free to move.
- An example in sodium chloride.
- Covalent bonding (in non metals)
- Small molecules. Simple molecular
- Low melting points
- Does not conduct electricity.
- An example is water.
- covalent (in non-metals)
- Cannot conduct electricity except graphite which has free electrons.
- High
- Diamond, graphite are examples.
- Giant molecules
- Metallic (in metals)
- High melting point
- Conducts electricity due to free electrons.
- Giant metallic structure
- Examples are zinc and copper.
- Ionic bond (Between metals and non metals
