Frequently Examined
The periodic table underpins all of GCSE Chemistry — it appears in almost every topic. Specific exam questions on "the periodic table" typically test: identifying group and period from electronic configuration, explaining why elements in the same group have similar properties, describing trends in reactivity for Groups 1 and 7, and distinguishing metals from non-metals. A favourite 3-mark question asks students to explain why a particular element is reactive by linking outer electron count to ease of gaining or losing electrons.
Edexcel 1CH0: Examined in Paper 1 (1CH0/1). Edexcel questions frequently ask you to use the periodic table to predict properties of elements, explain periodic trends, and link electronic configuration to group/period position. The development of the periodic table (Newlands, Mendeleev) is a common short-answer topic. In Edexcel-style questions, the command word "Suggest" appears frequently — use your chemistry knowledge to apply to an unfamiliar context.
This exam focus covers Exam Focus within The Periodic Table for GCSE Chemistry. Revise The Periodic Table in Atomic Structure for GCSE Chemistry with 22 exam-style questions and 24 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 11 of 13 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
