CIE IGCSE Combined Science C3 REVISION (Atoms, elements and compounds)

A lot of time and effort has gone into the design of this revision resource as it covers the very important Atoms, elements and compounds topic (C3) of the CIE IGCSE Combined Specification which will be examined in June and November 2020 and 2021. This topic tends to contribute a high volume of the questions in the examination papers as it contains fundamental understanding. The resource contains a detailed and engaging PowerPoint (87 slides) and associated worksheets, which have been differentiated to allow differing abilities the chance to complete the task. The range of activities that include exam questions, quick tasks and quiz competitions aim to cover as much of the content as possible but the following topics have received particular attention:

• Metals vs non-metals
• Using the proton and nucleon number to calculate the number of sub-atomic particles
• Atoms vs ions
• Drawing dot and cross diagrams for ionic compounds
• The structure of an ionic compound and the relation to its properties
• Drawing dot and cross diagrams for simple molecules
• Understanding of the terms solution, solvent, solute and soluble

Throughout the lesson, links have been made to other modules (e.g. Electricity and chemistry) so that students can see how they will be expected to make these connections. The detail of this lesson means that it can be used a number of times and is ideal for revision during the learning of C3, at the end of the topic or in the lead up to mocks or terminal exams.
