Atomica

Chemistry starts with the elements. ATOMICA makes them easier to explore, with a clear periodic table, approachable explanations and useful scientific details.
Browse all 118 elements in a full-table overview or focus view. Search by element name, symbol or atomic number, or use family filters to explore related elements.
Open an element to discover where it occurs, how people use it and what makes it interesting. Expand the science section for physical properties, electron information and source notes. Unfamiliar terms are explained in context, so you can follow the ideas as you read.
Element information is bundled in the app, so you can explore offline. Open reference links when you want to read more from the original sources.
Whether you’re studying chemistry or simply curious about the matter around you, ATOMICA offers a welcoming place to start exploring.
