Periodic Table: Elements Lab

Every element, beautifully made — and a study system that actually makes it stick. Periodic Table: Elements pairs all 118 elements with original illustrations, the real figures (atomic mass, electron configuration, isotopes with half-lives, emission spectra) and a spaced-repetition study system that schedules reviews based on estimated recall. 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. • Periodic trends explorer: watch atomic radius, electronegativity and more sweep across the table as a heat field. • Isotope-aware search: "c-14", "carbon 14" and "u235" all find the element. STUDY THAT STICKS • Spaced-repetition decks and flashcards that adapt to your recall. • Curriculum packs aligned to AP, IB, A-Level, GCSE and MCAT. • Custom drills and a Test Rescue mode for the night before an exam. • A study streak, readiness and mastery tracking — all on your device. TOOLS • Molar-mass calculator that parses real formulae, hydrates and brackets included. • 3D atom view. Element-of-the-day and full-table home-screen widgets. • Teacher / projector mode for the classroom. PRIVATE BY DESIGN • No accounts. No adverts. No analytics. No tracking.
