Atomic Structure Simulator Interactive
Explore three-dimensional representations of atoms and the periodic table. Students select elements and inspect their protons, neutrons, electrons, shell arrangements and element classifications. The full interactive is available to licensed Education Universe users.

Learning outcomes
- Identify protons, neutrons and electrons
- Relate atomic number to proton number
- Compare shell structures across elements
Teaching guidance
Use the visual model to discuss where it is a simplified representation rather than a quantum-mechanical depiction of an atom.
