Tiny particles dancing, snapping together, breaking apart. Build them, bond them, heat them up — see chemistry happen with your own hands.
Add protons, neutrons, and electrons to your atom. Watch the element change as you go. Try to build something that exists in real life!
Electrons stack into shells and subshells from the inside out: the closest, lowest-energy spot fills first. Add electrons and watch where each one lands.
These fuzzy shapes are where an electron is most likely to be. A card glows for the subshell your atom is filling right now.
Each period is a row, each group is a column. Click any tile to see its atomic structure up close.
Drag one atom toward another. If they're a metal and a nonmetal, you'll see an ionic bond — electrons hop across. Two nonmetals? A covalent bond — electrons shared.
Particles never sit still. Slide the temperature and watch solid, liquid, and gas reveal themselves.
No grades here — just curiosity. Stuck? Tap the hint button. You'll be reading the periodic table like a chemist in no time.
