Chemistry does not have to be boring, confusing or stressful. Kemistri is an interactive chemistry learning game that helps students understand important concepts, practise problem-solving and enjoy learning through guided gameplay. BUILD UNDERSTANDING, NOT JUST MEMORY Kemistri acts as a friendly learning guide, helping you build strong chemistry foundations instead of simply memorising facts and formulas. Through interactive challenges, you can: โ€ข Explore the periodic table โ€ข Understand atomic structure and electron arrangement โ€ข Build electronic configurations step by step โ€ข Apply electron-filling rules โ€ข Construct molecules and chemical structures โ€ข Identify different types of chemical reactions โ€ข Practise balancing chemical equations โ€ข Explore periodic trends โ€ข Learn VSEPR theory and molecular geometry โ€ข Understand hybridisation โ€ข Explore acids, bases and the pH scale โ€ข Solve chemistry problems logically Helpful explanations and hints guide you when needed, keeping learning rewarding rather than frustrating. INTERACTIVE CHEMISTRY ACTIVITIES Kemistri contains a growing collection of chemistry games and challenges, including: โ€ข Placing elements in their correct periodic-table positions โ€ข Arranging elements into the correct groups and periods โ€ข Building electronic configurations for different atoms โ€ข Filling atomic orbitals using electron rules โ€ข Constructing molecules โ€ข Recognising reaction types โ€ข Balancing chemical reactions โ€ข Exploring atomic radius, ionisation energy and electronegativity โ€ข Learning molecular shapes and chemical bonding โ€ข Experimenting with interactive chemistry tools Each activity introduces concepts through interaction, repetition and progressively more challenging levels. DAILY LEARNING AND DISCOVERY Keep learning with daily chemistry challenges, build your study streak and unlock achievements as you progress. Explore science legends, chemistry history, fascinating facts and jokes that make learning more memorable and enjoyable. MADE FOR CHEMISTRY REVISION Kemistri is suitable for: โ€ข School chemistry revision โ€ข Students beginning to learn chemistry โ€ข GCSE, A-level and equivalent learners โ€ข Daily concept practice โ€ข Curious learners who enjoy science Its calm, game-based approach makes revision more enjoyable and helps students practise without the pressure of a traditional test. LEARN AT YOUR OWN PACE Whether chemistry is completely new to you or you want another way to revise familiar topics, Kemistri allows you to progress gradually. Start with the fundamentals, complete interactive challenges and build confidence as new topics are introduced. BUILT WITH PASSION Kemistri is created by a small independent team focused on making science education more engaging and accessible. Your support helps us develop new chemistry content, improve the experience and expand language access.

Periodic Table Master

Features
Read full description

Periodic Table Master is the ultimate reference and learning tool for anyone curious about the elements that make up our universe. Completely free โ€” 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, color-coded periodic table. Each element is grouped by category โ€” alkali metals, noble gases, transition metals, and more โ€” 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 recolor the entire table by any numeric property โ€” electronegativity, atomic radius, density, melting point, boiling point, thermal conductivity, ionization 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 gray. Tap again to return to category colors. 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, ionization energies, and more. Over 80 elements include a real-world image showing exactly what the element is used for โ€” 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 โ€” 1, 2, 3, 4, or 5 minutes, or play with no timer at all. Score +1 for a correct answer, โˆ’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 โ€” tracked separately for each duration โ€” 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 Color-coded element cells by category Property heat map to visualize trends across the periodic table Optional two-letter category labels for each cell โ€” ideal for color-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 โ€” 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 used for โ€” Periodic Table Master has you covered.
