What examiners said
The group number of the alkali metals was almost universally known.
— Examiner report, May/June 2025, 0620/42 Q5(a) (Cambridge)
Candidates performed well on (i) to (iii) which were based upon trends seen in Group I metals. Only a few candidates did not opt for either the top element or the bottom element of the group. In (iv) and (v), most candidates knew potassium burned with a lilac flame and was found in fertilisers.
