PeriodicTableHub is a free educational web resource designed to make chemistry accessible and engaging for everyone. We provide detailed, scientifically verified information about all 118 chemical elements of the periodic table — from Hydrogen to Oganesson.
Our Mission
We strive to create the most user-friendly chemistry resource that combines scientific accuracy with interactivity and modern design. Each element page features a complete set of physical and chemical properties, electron configuration, isotopes, discovery history, applications, and fun facts.
Our project is completely free, requires no registration, and works offline thanks to Progressive Web App (PWA) technology. You can install PeriodicTableHub on your phone or tablet just like a regular app.
