CAIE IGCSE Chemistry 8.1 Arrangement of elements Question Bank

Practise reading Periodic Table positions, linking groups and periods to electron structure, ion charges and metallic character.

Exam points

use group and period positions to identify elements and likely ion charges
explain similar chemical properties from the same number of outer-shell electrons
compare metallic character across a period and reactivity trends down groups
