Atom Builder

Build atoms proton by proton

Drop in protons, neutrons, and electrons one at a time and the element shifts under your hands as the count changes. Stack the nucleus, fill the shells, and tinker with the particle balance to see what each one actually does.

What it would do

• ✓Add protons and the element changes with each one
• ✓Place neutrons and electrons to balance the atom
• ✓See the nucleus and shells redraw as you build

Signaling interest is free and non-binding — it just tells the maker you'd use this.
