The Periodic Table — IGCSE Science - Combined (0653) questions by topic
Questions here test recall of group and period trends: identifying gases produced when Group I metals react with water, comparing melting points and conductivity between transition elements and Group I elements, and picking out correct statements about transition-element properties from a list. Explain, state and identify are the top command words, each rewarding a named property or product rather than a broad description of the Periodic Table.
This set holds 18 real questions from 2023 to 2025 papers, worth 1 to 11 marks, mixing single-mark multiple-choice with short written answers. Submitting each response for instant marking helps confirm whether a stated trend, such as which element reacts fastest with water, actually matches the pattern the mark scheme expects across the whole group.
