Build an Atom Workshop – Interactive Atom Structure Simulation (KS3/GCSE Chemistry)

Interactive KS3/GCSE Chemistry resource for teaching and revising atomic structure.
Students build atoms by entering the correct numbers of protons, neutrons and electrons. When the values are correct, the particles move into place and the atom is constructed visually, helping students see the relationship between the nucleus and electron shells more clearly.
The resource is also useful for extending discussion into ions and isotopes, allowing students to explore how changing electron or neutron number affects the atom.
This makes the workshop useful for:

• introducing atomic structure
• checking understanding
• classroom modelling
• revision and retrieval practice
• independent student exploration
  Useful for:
• KS3 Science
• GCSE Chemistry
• Protons, neutrons and electrons
• Atomic structure
• Electron shells
• Ions
• Isotopes
  The resource runs directly in a web browser with no software or installation required.
