Table Lab

Click any element. The card shows its name, symbol, atomic number, group, period, and family. There is no quiz until you start a round.

Lab tip: Color is a hint, not the only clue. Turn on color-blind mode to add patterns and family letters.

Keyboard: arrows move, Enter opens a card, / jumps to search.
