Atom

Learn about Atoms by building them with particles

Atom is a simulation of the commonly used atomic model, where you can play with individual protons, neutrons, and electrons to see how they affect the properties of an atom.

Use the built-in periodic table to quickly access all 118 elements along with their isotopes and electron configurations.

Modules are still being developed for the learn section, but check out the new minigames and history of the atomic model.
