Updated for 2025 AQA GCSE Chemistry and Combined Science (8462 / 8464).
A complete, fully editable lesson covering C2.5 – Explaining Trends from the AQA specification.

Students learn how reactivity changes in the alkali metals (Group 1) and halogens (Group 7), and why these trends occur based on atomic structure, electron shielding, and distance from the nucleus.
This lesson brings together prior C2 content, helping students confidently link periodic position → electron configuration → reactivity for Paper 1 – Atomic Structure and the Periodic Table.

Includes free AI long-answer feedback – students can submit extended-response questions online and receive instant, AQA-aligned WWW/EBI feedback to improve structure, reasoning, and scientific language.

What’s Included
  • Editable PowerPoint with diagrams, explanations, and step-by-step reasoning
  • Printable / editable worksheets with model answers (Foundation → Higher)
  • Exam-style questions with mark schemes and sample responses
  • Retrieval starter and plenary quiz
  • AfL checkpoints and differentiated challenge tasks
  • Homework / revision activity
  • Comprehensive teacher answer key

All resources are fully editable and ready to teach.

Topics Covered
  • Trends in Group 1 (alkali metals) – increasing reactivity down the group
  • Trends in Group 7 (halogens) – decreasing reactivity down the group
  • Electron shielding and nuclear attraction
  • Energy required to lose or gain outer electrons
  • Atomic radius and its effect on reactivity
  • Comparing trends across groups using atomic structure explanations
  • Applying structure–reactivity reasoning to exam-style questions
Why Teachers Choose This Lesson
  • Fully aligned with AQA Chemistry (8462 / 8464)
  • Clear explanations connecting atomic structure to periodic behaviour
  • Strong exam focus with structured reasoning practice
  • Differentiated for Foundation and Higher tiers
  • Supports AI-enhanced feedback for extended-answer development
  • Ready-to-teach and time-saving
Suitable For
  • GCSE Chemistry and Combined Science Paper 1
  • Classroom delivery, revision, or cover lessons
  • Department resource banks and curriculum standardisation

To be honest, I bought the resource as I have never taught the topic before (but I am an experienced science teacher) and needed something that would speed up my lesson planning. I really cannot see how this helpful for me.
