Kemistri Atom Builder
Don’t Memorise Atoms.
Build Them.
Add protons, neutrons and electrons and discover what each particle actually does. Atomic structure becomes something you can change, see and explore.
Build an Atom →Learn by changing things.
Experiment with the particles and immediately see how your atom responds.
PROTONS
Change the element.
Add or remove protons and discover why atomic number determines the identity of an element.
ELECTRONS
Explore charge.
Change the number of electrons and see how ions are created.
NEUTRONS
Discover isotopes.
Change the neutron count while keeping the same element and explore isotopes visually.
