Explore the building blocks of matter with Periodic Table: a visual chemistry reference with all 118 elements, available offline after installation. START WITH THE CLASSIC TABLE Browse 18 groups and 7 periods, with separate lanthanide and actinide rows. Tap any element to open its card, or move and zoom the table to explore. SEE THE ESSENTIALS AT A GLANCE Large symbols, clear numbers and color-coded categories make element cards easy to scan. Explore atomic mass, protons and electrons, electron shells, electron configuration, electronegativity, density, melting and boiling points, and position in the table. UNDERSTAND VALENCE Compare typical valences with signed oxidation states and selected compound examples. Valence information covers 80 elements, with 125 examples and notes explaining the limits of the data. FIND WHAT YOU NEED Search by element name, symbol or atomic number. Filter by category or physical state and use the color legend to understand the table. DISCOVER THE STORIES Read concise information about discovery, names, uses and selected isotopes. Unknown or estimated properties are identified, and element cards include sources and notes. CHOOSE YOUR LANGUAGE Use English, Spanish, Arabic, French, Hindi, Thai or Russian. English is the default; your language choice is saved on your device. Arabic supports right-to-left reading while chemical formulas keep their standard direction. MAKE IT COMFORTABLE Switch between light and dark themes. The layout adapts to iPhone and iPad in portrait or landscape. No account, ads or in-app purchases. The app includes its reference data, translations and fonts, so its core features work without an internet connection. Designed for learning and quick reference. Isotopes and valences are selected examples, not exhaustive catalogs.
