This complete year 12 lesson on the periodic table includes the history of the periodic table, the features of the modern periodic table and periodicity. The resource features a 20 slide animated PowerPoint that illustrates the concepts in a lively and visual way and includes a starter, a jigsaw discussion activity on the periodic table with a quiz, and a true-false quiz that could be used as a plenary or a recap at the start of the next lesson. A 4 page worksheet and answers to all exercises, quizzes and discussion questions are provided. This resource is part of a series covering the OCR AS Chemistry specification and relates to the following sections: Module 3 – Periodic table and energy Part 1 – The periodic table 3.1.1 Periodicity Content covered: • The history of the periodic table, including Newlands’ and Mendeleev’s contributions • The structure of the modern periodic table – periods, groups and blocks • Relationship between electron configuration and the periodic table • Periodicity – the variation in properties when plotted against atomic number • Periodicity and metallic character • Metal and non-metals Duration: 1-2 lessons Please review!

A set of five problems to practise identifying organic compounds from % composition, infrared (IR) spectroscopy and mass spectrometry. Suitable for AS or A2 level, this type of exercise is good preparation for exam questions on identifying organic compounds using combined spectroscopic techniques. It could also be used for revision or consolidation of IR spectroscopy and mass spectrometry, as well as for assessment for learning. Full answers to all the problems are provided. This resource was developed primarily for the OCR A level Chemistry specification but is useful for all specifications. It relates to the following sections : AS: Module 4 – Core organic chemistry Part 2 – Alcohols, haloalkanes and analysis 4.2.4 Analytical techniques A2: Module 6 – Organic chemistry and analysis Part 3 – Analysis 6.3.2 Spectroscopy (Combined techniques) Please review! Content covered • Calculating empirical formula from % composition • Calculating molecular formula from empirical formula and molar mass, using the molecular ion peak on the mass spectrum • Using the infrared (IR) spectrum to identify bond stretches and hence functional group(s) present • Drawing structural formulae consistent with the molecular formula and IR data • Using mass spectrum to distinguish between the suggested structural formulae • Identifying fragments in the mass spectrum Duration: 1 part lesson and/or independent study Links Please see also: infrared (IR) spectroscopy - A level https://www.tes.com/teaching-resource/infrared-ir-spectroscopy-a-level-home-learning-self-study-12315096 mass-spectrometry - A level https://www.tes.com/teaching-resource/mass-spectrometry-a-level-home-learning-self-study-12287938 mass spectrometry summary AS home learning https://www.tes.com/teaching-resource/mass-spectrometry-summary-as-home-learning-coronavirus-12287495
