Store description excerpt
Periodic Table Master is the ultimate reference and learning tool for anyone curious about the elements that make up our universe. Completely free — no ads, no accounts, nothing locked behind a purchase. There's an optional tip jar if you'd like to support development. Explore the Full Periodic Table Browse all elements in a beautifully designed, colour-coded periodic table. Each element is grouped by category — alkali metals, noble gases, transition metals, and more — making it easy to spot patterns and relationships at a glance. Pinch to zoom in for detail or out for the full picture, and tap any element to dive deeper. Property Heat Map Tap the thermometer icon to recolour the entire table by any numeric property — electronegativity, atomic radius, density, melting point, boiling point, thermal conductivity, ionisation energy, atomic mass, or electron affinity. A blue-to-red gradient reveals trends and outliers across the periods instantly. Elements with no data for a property appear grey. Tap again to return to category colours. Detailed Element Profiles Every element has a full profile page covering atomic mass, density, melting and boiling points, electron configuration, oxidation states, atomic radius, natural occurrence, biological role, ionisation energies, and more. Over 80 elements include a real-world image showing exactly what the element is used for — from copper piping to green fireworks, solar panels to jet engines. Test Your Knowledge Challenge yourself with a timed quiz covering all 118 elements. Choose your duration in Settings — 1, 2, 3, 4, or 5 minutes, or play with no timer at all. Score +1 for a correct answer, −1 for wrong, and 0 to pass. Questions span symbols, names, atomic numbers, categories, periods, blocks, electron shells, oxidation states, biological roles, real-world uses, and crustal abundance. Wrong answers are penalised, so accuracy matters. Beat your high score — tracked separately for each duration — and work towards a perfect reaction. Search Instantly Looking for a specific element? Use the built-in search to find any element by name, symbol, or atomic number. Matching elements light up on the table while others fade away, making it effortless to locate what you need. Beautiful and Informative Colour-coded element cells by category Property heat map to visualise trends across the periodic table Optional two-letter category labels for each cell — ideal for colour-blind users Bohr model diagrams showing electron shell structure Spectral line images for elements that produce them Ionisation energy charts Electron configuration with Unicode superscripts Crustal abundance data for over 80 elements Works Completely Offline All content is built into the app — no internet connection is ever required. There are no subscriptions and no data collected or shared. Whether you are a student revising for exams, a teacher looking for a classroom reference, or simply someone who has always wondered what tungsten is
