Edexcel GCSE Combined Science Topic C1 (Key concepts in chemistry) REVISION

This is a fully-resourced revision lesson that uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to help the students to assess their understanding of the sub-topics found within Topic C1 (Key concepts in chemistry) of the Edexcel GCSE Combined Science specification.

The sub-topics and specification points that are tested within the lesson include:

• Describe how the model of the atom has changed over time with the discovery of the subatomic particles
• Describe the structure of an atom and know that atoms contain the same number of protons as electrons
• Calculate the number of protons, electrons and neutrons when given the atomic and mass number
• Identify elements as metals or non-metals
• Predict the electron configuration of the first 20 elements
• Explain how ionic bonds are formed by the transfer of electrons
• Explain the structure of an ionic compound as an ionic lattice
• Explain how a covalent bond is formed
• Be able to draw dot and cross diagrams for simple covalent structures
• Describe the structure and properties of graphite and diamond
• Calculate the relative formula mass
• Explain the law of the conservation of mass
• Calculate the concentration of a solution
• Recall Avogadro’s constant and use in mole calculations

Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual GCSE terminal exams
