Frequently Examined

Atomic structure is examined in virtually every GCSE Chemistry paper. Expect 4-8 marks dedicated to this topic per paper. Common question types include: calculating numbers of protons, neutrons, and electrons from atomic and mass numbers; explaining the development of the atomic model (a popular 4-6 mark extended question); defining and giving examples of isotopes; and comparing subatomic particles. Higher tier students may also be asked about relative atomic mass calculations from isotope data.
