The Periodic Table — IGCSE Sciences - Co-Ordinated (0973) questions by topic

The Periodic Table questions ask about helium's reactivity and outer-shell electrons, general properties of noble gases, copper's properties as a transition element, and identifying which substance forms a basic oxide and coloured compounds, worth from 1 to 10 marks in this IGCSE Co-ordinated Sciences set.

Identify, state and suggest lead the command words, with deduce and complete also common: deduce a property from a group or period position, not recall alone. 22 real questions from 2023 to 2025 papers sit here. Submitting each answer for instant marking flags an outer-shell electron count given for the wrong group before it is repeated.
