This explaining trends 6 mark exam question is a great resource to assess students understanding of the atomic structure and the periodic table topic as part of the AQA GCSE Chemistry course. I use it as part of the AQA GCSE Chemistry revision for paper 1 or at the end of the 1.11 Explaing trends lesson. Sometimes I use it as a starter with my A Level students (OCR Chemistry A). The resource is a common AQA exam question.
