Periodic Table - GCSE Chemistry
Periodic table
The periodic table is central to GCSE Chemistry. Learners use it to identify elements, atomic numbers, mass numbers, groups, periods, patterns in reactivity, and links between electron structure and chemical behaviour.
It supports work on atomic structure, bonding, Group 1, Group 7, Group 0, transition metals, formulae, equations, and quantitative chemistry.

Learners should use it to
- find atomic numbers and relative atomic masses
- identify metals, non-metals, groups, and periods
- predict electron arrangements for atoms and ions
- explain trends in Group 1, Group 7, and Group 0
- support calculations involving formulae and equations
