Elementa Periodic Table

Elementa is a complete, offline periodic table reference and quiz built for anyone curious about chemistry — students, teachers, and lifelong learners alike. Every one of the 118 known elements is bundled right into the app: no internet connection is ever needed. EXPLORE THE FULL TABLE Browse the classic 18-column periodic table, colour-coded by category — alkali metals, transition metals, metalloids, noble gases, lanthanides, actinides, and more. Tap any tile to open a detail card with its atomic number, symbol, atomic mass, period, group, block, and a one-line fact that actually teaches you something memorable about it. SEARCH AND BROWSE Prefer a plain list? Switch to the searchable List tab and find any element instantly by name, symbol, or atomic number. LEARN THE LAYOUT The Guide tab explains what the colour categories mean and how the s, p, d, and f electron blocks are organized, so the table stops looking like a wall of boxes and starts making sense. TEST YOURSELF The Quiz tab turns the whole dataset into a fast, ten-question mini-game with three question styles — name the symbol, spot the category, and identify the element from a clue. Build a streak, beat your best score, and watch it get saved right on your device. TRACK YOUR PROGRESS The Awards tab unlocks badges as you explore more elements and sharpen your quiz results, from opening your very first element card to naming all 118.
