Periodicity
infoWhy this? Extending periodic reasoning to the properties and reactions of elements and their compounds connects electronic structure, bonding, and chemical behaviour. It enables us to explain patterns and recognise where simple trends require more detailed explanations.
scheduleWhy now? The Year 12 studies of periodicity, halogens, and Group 2 now provide examples against which to compare trends across periods and down groups. Revisiting these connections prepares us for the more varied oxidation states, bonding, and reactions encountered in transition metal chemistry.
