Chemistry
Transition metals (A-level only)
AQAA-Level
7405
Transition metals turn abstract electron structure into colour, shape, redox chemistry and industry. This exam-focused A-level guide shows exactly how to earn marks for complexes, ligand substitution, colour, catalytic cycles and the linked aqueous-ion practical. It also flags an important scope point: 3.2.5 is A-level only, so use it as a GCSE-to-A-level bridge rather than GCSE core content.
Chemistry
Using resources
AQAGCSE
8462
This topic covers how we sustainably use Earth's resources, from making water safe to drink, to extracting metals without traditional mining, to evaluating the environmental impact of products. It's heavily tested in exams because it links core chemistry to real-world environmental challenges.
