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