This lesson is designed for the NEW AQA Chemistry GCSE, particularly the 'Atomic Structure & Periodic Table' SoW.

This lesson starts with a diagram of the electronic configuration of fluorine, chlorine and bromine and pupils need to think > pair > share their ideas about any trends/patterns they can see as they go down the group. The trend in the electronic configuration and what this means in terms of reactivity is then outline on the next slide, pupils are then asked to answer questions about this. The answers to which will be revealed so pupils can check their answers.

To summarise what they have learnt so far pupils can complete a fill-in-the-blank task, then they will watch a video which will identify some of the properties of the different elements found in the halogen group.

Once this work has been self-assessed pupils will then be shown what a displacement reaction is and will be given a worked example to demonstrate how it works. Once you feel confident that pupils have understood when a displacement reaction will take place they can complete some word equations to show the products of such reactions. This can then be marked and any misconceptions addressed.

The plenary task is a true or false task which you could conduct as a class or ask pupils to complete in their books and then mark.
