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

This lesson begins with an introduction into the sub-atomic particles that make up an atom, pupils will need to fill in a diagram and statements to describe the position of each of these particles. Pupils will then be shown the charges and relative mass of each of these particles for a couple of minutes during a 'memory test' activity, they will then try and copy the information down into their books from memory.

Next is a mid-lesson progress check where pupils will need to answer questions off the board in pairs.

In the next half of the lesson pupils are introduced to the idea of atomic and mass numbers, they are firstly asked to use their periodic table to identify the atomic and mass numbers of certain elements. This work is self-assessed and then pupils are asked to think about how the number of neutrons could be calculated, once revealed pupils are then given a large table to complete to identify the atomic number mass number, plus the number of protons, neutrons & electrons for the first 20 elements.

The plenary task is an exit card where pupils can identify the areas in which they feel confident with this topic and those areas they feel they need more practise with.

All resources are included at the end of the presentation.
