What examiners said
The majority of candidates could use the information to give the correct order of reactivity of the metals.
— Examiner report, May/June 2025, 0654/42 Q7(d)(i) (Cambridge)
Sometimes candidates tried to write a singular product incorporating magnesium, sulfur, oxygen and zinc.
— Examiner report, May/June 2025, 0654/42 Q7(d)(ii) (Cambridge)
Several candidates recognised that the metal atoms were of different sizes. Fewer were able to explain that this prevented the layers of atoms sliding over each other.
