- Simple molecular substances
- 1. Atoms form very strong covalent bonds to form small molecules of several atoms.
- 2. The forces of attraction between these molecules are very weak.
- 3. The result of the weak intermolecular forces is that it has a low melting and boiling point.
- 4. Most molecular substances are gases or liquids at room temperature, but they can be solid.
- 5. Molecular substances don't conduct electricity - there are no ions so there is no electrical charge.
