Every element, beautifully made - and a study system that actually makes it stick. Periodic Table: Elements pairs all 118 elements with original illustrations, real numbers, sourced isotope data, emission spectra, and a spaced-repetition study system that schedules each card for the moment you're about to forget it. Includes FSRS flashcards, 109 balance-checked reactions, a guided equation balancer, 3D atom view, macro-to-subatomic dive, and widgets. THE TABLE All 118 elements, each with original cover art, a plain-language story, and sourced data you can trust. Every element page shows where its facts come from. Pinch from the poster view into a data-rich focus grid, explore periodic trends, and search isotopes like c-14, carbon 14, and u235. STUDY THAT STICKS Spaced-repetition decks and flashcards adapt to your recall. Curriculum packs support AP, IB, A-Level, GCSE, and MCAT review. Custom drills and Test Rescue help focus study before an exam. Readiness and mastery tracking stay on your device. TOOLS Use the molar-mass calculator for real formulas, hydrates, and brackets. Explore a 3D atom view, element-of-the-day widgets, and classroom-friendly table tools. PRIVATE BY DESIGN No accounts. No ads. No analytics. No tracking. No cloud.
