C2: The Periodic Table and Periodicity
Official Cambridge & Imperial ESAT specification requirements for The Periodic Table and Periodicity on the Chemistry paper. Understand the syllabus boundaries, spot distractor traps engineered by examiners, and master the 2-step Sub-90 shortcuts that compress solve time well below the 88.8-second cutoff.
Official Syllabus Subtopics
Requirements specified in the UAT-UK framework
- 1Arrangement of elements by atomic number into periods and groups
- 2Valence electrons, oxidation states, and group trends
- 3Group 1 alkali metals: increasing reactivity down group
- 4Group 7 halogens: decreasing reactivity down group
- 5Group 0 noble gases: full outer valence shells and chemical inertness
- 6Metallic vs non-metallic character across periods
Sub-90 Exam Speed Tips
How top candidates solve this spec under the 88.8s clock
Reactivity INCREASES down Group 1 (greater shielding makes losing outer electron easier).
Reactivity DECREASES down Group 7 (greater shielding makes attracting an incoming electron harder).
Examiners engineer distractor options using common algebraic expansions and sign slips. Always test structural ratios or invariants before calculating arithmetic values.
