Cambridge IGCSE Chemistry 0620 syllabus for exams in 2026, 2027 and 20282026–2028

Practise linking group number to ion charge, ionic formulae and electron transfer in compounds formed by metals and non-metals.

How this is tested

  • use ion charges to choose formulae and simple ratios in ionic compounds
  • link Group I or Group VII position to electron loss or gain during ion formation
