Ionic compounds
Small molecules
Polymers
Giant covalent structures
Metals
Good conductors of electricity as solids
Do not conduct electricity as the molecules do not have an overall charge
Substances which are almost always solid due to very high melting points
Do not conduct electricity (except graphite)
Example: methane
Long chains of connected monomers that are solid at room temperature
High melting and boiling points due to strong electrostatic forces between oppositely charged ions
Usually quite soft when pure, but can be made harder by mixing
Can conduct electricity as liquids or when dissolved in water
Easily bent and shaped as atoms are arranged in layers
Example: diamond
Usually gases or liquids
Example: sodium chloride
Example: poly(ethene)
Example: iron
Good thermal conductors due to delocalised electrons
Weak intermolecular forces
