GCSE Chemistry
Bonding & Structure
Bonding & Structure is a core strand in Chemistry. Work through the topics below in any order, or follow your course — each guide includes explanations, common mistakes and exam-style practice.
Topic guides
Ionic Bonding
Ionic Bonding is best understood as electron transfer followed by electrostatic attraction.
Open guideCovalent Bonding
Covalent Bonding is about shared pairs of electrons, but the bigger GCSE challenge is linking bonding to structure and then to properties.
Open guideMetallic Bonding
Metallic bonding is the force of attraction between the positive metal ions and the delocalised electrons in a metal lattice.
Open guideStates of Matter & Bonding
The three states of matter are solid, liquid, and gas.
Open guideStructure & Properties of Giant Lattices
Giant lattice structures are found in ionic compounds, covalent network solids (like diamond), and metals.
Open guideDiamond, Graphite & Graphene
Diamond, graphite, and graphene are allotropes of carbon, meaning they are different structural forms of the same element.
Open guideNanoparticles
Nanoparticles are particles with a size between 1 and 100 nanometers.
Open guidePolymers
Polymers are large molecules made up of many small, repeating units called monomers.

Revision strategy
Students often slip on the details explained in our guides — read the “common mistakes” section in each topic.
- Alternate between reading a guide and doing timed questions — don’t only re-read notes.
- Return to this hub anytime; new guides appear automatically as we publish them.
