AQA 8464 Combined Science | End-of-Topic Challenge

This focused GCSE Chemistry worksheet is designed as a final assessment task for C2 – The Periodic Table, covering the key concepts required by the AQA specification.

The worksheet challenges students to apply their understanding of:

• The development of the periodic table
• Electronic structure and group trends
• Group 1 (alkali metals)
• Group 7 (halogens)
• Explaining trends using shells and shielding
• Transition element properties

Rather than simple recall, this task requires students to identify elements from clues, write electronic configurations, determine groups, and explain periodic trends using structured scientific reasoning.

What’s Included:
✔ Element identification challenge
✔ Electronic configuration practice
✔ Group placement questions
✔ Reactivity trend explanations (Group 1 & Group 7)
✔ Extended comparison question (includes transition metals)
✔ Full mark scheme with levelled 6-mark guidance

• Skills Developed
  Linking atomic number to electronic structure
  Explaining trends using shielding and nuclear attraction
  Comparing different groups in the periodic table
  Exam-style extended writing
  Retrieval and application of core C2 knowledge

Perfect For:
End-of-topic revision
Pre-mock assessment
GCSE intervention sessions
Homework consolidation
Small group tutoring
Retrieval practice before Paper 1

This worksheet works particularly well as a final C2 consolidation task, allowing teachers to quickly assess strengths and misconceptions before moving on.
