The Periodic Table — IGCSE Chemistry (0971) questions by topic
Periodic Table questions test recognition of group and period properties: naming what Group VII elements are called, working out why a displacement reaction between a halogen and a halide occurs, identifying which properties belong to a set of transition-metal-like elements, and deducing the electron, neutron and proton count for a named isotope such as boron-11. State, identify and give want short, precise factual answers, while calculate and complete cover numerical particle-counting work.
29 real questions from 2025 papers sit on this page, worth from 1 to 14 marks. Because multiple-choice questions here hinge on distinguishing subtly different explanations rather than picking a familiar-sounding option, submitting attempts for instant marking flags quickly whether a plausible-looking distractor, such as a wrong reason for a displacement reaction, has been chosen instead of the option supported by the actual chemistry.
