What examiners said
Comprehensive responses • Many candidates knew the correct period for titanium using the Periodic Table. Limited responses • Some candidates confused the period and mainly thought that titanium was in period 3. They had forgotten that hydrogen and helium are in period 1.
— Examiner report, February/March 2026, 0620/32 Q3(a)(i) (Cambridge)
Comprehensive responses • Most candidates could work out the number of neutrons and protons in the isotope of titanium. Limited responses • A few candidates confused the number of neutrons and thought that they were the mass number of 50.
— Examiner report, February/March 2026, 0620/32 Q3(a)(ii) (Cambridge)
Comprehensive responses • Most candidates identified 5. Limited responses • Some candidates attempted to write the full electron configuration.
