ControlsModel-timeline slider (5 stops: Dalton 1803 -> Thomson 1904 -> Rutherford 1911 -> Bohr 1913 -> Quantum 1926) smoothly morphs the atom between historical models; element buttons (H / He / C / Ne) change proton, neutron and electron counts and shell filling; Auto-play toggle cycles through the five models automatically every ~2.6s; Orbits toggle shows or hides the Bohr shell rings.

⚙ Under the hood

Scrub through five historical models of the atom — Dalton's solid sphere, Thomson's plum-pudding, Rutherford's nuclear planetary model, Bohr's quantized orbits and the modern quantum probability cloud. Switch chemical elements and watch electron count, shell structure and orbit radius morph live in 3D.
