## What is Periodica?

Periodica is a beautifully designed, interactive periodic table for anyone who loves chemistry — students, teachers, and the endlessly curious.

Tap any element to dive into a rich detail page: watch an animated 3D atomic model spin, explore electron shells (Bohr model), and read clear summaries alongside real physical data.

FEATURES

• Complete periodic table — all 118 elements, color-coded by category, with a smooth zoomable layout.
• Interactive 3D atom — rotate a SceneKit-powered atomic model for every element.
• Electron shells & configuration — animated Bohr-model shells plus full electron configuration diagrams.
• Real physical data — atomic mass, melting/boiling points, density, electronegativity, ionization energy and more.
• Isotopes & compounds — natural abundance, half-life, and common compounds for each element.
• Search & browse — find any element by name, symbol, or atomic number in an instant.
• Light & dark themes — comfortable viewing day or night.
• 20 languages — follows your system language automatically, or pick one in Settings. Element names, categories and compounds are localized too, not just the interface.
• Built for iPhone and iPad — on iPad the element list, the full periodic table and the element detail view sit side by side, adapting to portrait and landscape.

Whether you're revising for an exam, teaching a class, or just satisfying your curiosity about the building blocks of the universe, Periodica puts the whole periodic table in your pocket.
