CAIE IGCSE Physics 5.1.1.1 Structure of an atom in terms of a
Practise describing neutral atoms as a small positive nucleus with electrons in orbit, using diagrams and nuclide information.
How this is tested
- identify the nucleus and orbiting electrons in atomic diagrams or labelled models
- state that protons and neutrons are in the nucleus while electrons orbit around it
- use nuclide data to infer electron number and neutrality for a named atom
