CAIE IGCSE Chemistry 8.5.1 Group VIII noble gases as unreactive
Cambridge IGCSE Chemistry 0620 syllabus for exams in 2026, 2027 and 20282026–2028

Practise linking noble gas unreactivity to full outer electron shells, monatomic particles and Periodic Table position.

How this is tested

  • choose statements that match noble gases: full outer shells, monatomic gases and unreactive behaviour
  • explain unreactivity from electronic configuration, avoiding distractors
