This activity introduces oxidation numbers by giving a conceptual foundation for them in terms of electron accounting and polar bonds. It then shows how the model used so far needs refining.
Chemistry for the gifted and talented is a refreshingly challenging educational book containing a wide range of differentiated activities for use in school and college.
Show students how chemistry is upcycling plastic monomers into higher value alternative products
Use the latest research to help your students form correct mental images when predicting molecular geometries
Worksheet to develop understanding of the pH scale and apply it in the context of ocean acidification. Extension questions provide more challenge on carbonic acid and acid base equilibrium, leading to a research task on the consequences for marine organisms.
Hone your students’ observation skills by asking them to observe two microscale reactions: neutralising citric acid and creating a lead iodide precipitate
Research and presentation activity based on catalysts and reaction conditions in the context of sustainable industry.
