What examiners said
Few candidates were able to state that argon is very unreactive due to a full outer shell of electrons.
— Examiner report, February/March 2023, 0654/32 Q5(b)(ii) (Cambridge)
Some candidates were able to suggest a use for argon gas. Others confused argon with helium and suggested filling balloons.
— Examiner report, February/March 2023, 0654/32 Q5(b)(iii) (Cambridge)
