Definition
- Strong electrostatic forces hold the ions together.
- High temperature is needed to break these bonds.
- Ionic substances are solid at room temperature.
- They have high melting and boiling points.
- When dissolved the ions are free to move so can carry electrical charge.

Definition
- Metallic atoms arranged in layers can slide over each other when force is applied.
- This makes them bendable without breaking.
- Shape memory allows can be deformed and return to their original shape when heated.

Definition
- The covalent bonds between the atoms are strong so they are hard to break.
- The intermolecular forces between molecules are much weaker, meaning simple structures can easily be broken.
- This gives them low melting and boiling points.
