This GCSE Chemistry revision module focuses on chemical bonding and the resultant structures that dictate material properties. The course details the formation of ions, the principles of ionic and covalent bonding, and the relationship between bonding type and physical properties. Key topics include: the structure of giant ionic lattices, simple molecular substances, polymers, and giant covalent networks (with a detailed look at carbon allotropes like Diamond and Graphite). The module concludes with an analysis of metallic bonding and the particle theory explaining the three states of matter and changes of state.
