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