Electronic Structure and the Periodic Table
To predict how an element will react, we must look at its atoms. The Periodic Table is organized so that elements with similar properties are placed in vertical columns called groups, while horizontal rows are called periods.
Step-by-step lessons covering OCR GCSE Chemistry Predicting chemical reactions for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Foundation Tier) or Paper 3 and Paper 4 (Higher Tier) format. Nail the core quantitative topics — moles, balancing equations and calculations — early on, since they underpin higher-tier questions across every paper and topic.
