What examiners said
This question proved demanding. Most candidates recognised that there were delocalised electrons, but far fewer understood that positive zinc ions were also shown. These were often described as particles, atoms or metal. Few candidates correctly mentioned electrostatic attraction.
— Examiner report, May/June 2025, 0973/41 Q7(f) (Cambridge)
Bauxite was not well known as the ore of aluminium. Iron or iron ore were often incorrectly suggested.
— Examiner report, May/June 2022, 0973/31 Q5(c)(i) (Cambridge)
Many candidates confused conserved with preserved and omitted to mention anything about aluminium ore being a finite resource.
