WorldInside an AtomZoom from a drop of water to a proton — then build elements, ions and bonds
WorldAtomic Spectra & StarlightSplit lamp and star light with a prism, drop an electron down hydrogen's ladder, and read a star's heat off its colour
WorldChemical Bonding & MoleculesSnap atoms together by valency and let the shape settle itself — bond springs and repelling electron domains give methane 109.5°, water 104.5°, SF₆ 90°, all measured, none looked up
