In this unit we look at the chemicals that we can extract from the Earth.
The unit is split into 4 parts…

  • In unit C3.1 we look at the structure of the metals and the model we use to explain metallic bonding.
  • In unit C3.2 we look at the different reactivity of metals and how we use the reactivity to decide how to extract metals from rocks.
  • In unit C3.3 we look at the process of electrolysis and how it works.
  • In unit C3.4 we look at crude oil, how we separate it and use it to make new materials.
