§ 01 What is Atomurus?
Atomurus is a browser-based chemistry laboratory. It brings together an interactive periodic table with all 118 elements, Explore articles, 3D viewers and basic calculators that run in your browser with no account. A free account saves your study; Atomurus Pro is for solving, analyzing and experiment-grade workflows.
§ 02 Our mission
We believe the periodic table and chemistry fundamentals shouldn't sit behind a paywall or an app store. Atomurus is built around three principles:
- Open access. The periodic table, element pages, articles, molar mass and dilution stay open with no account.
- Scientific accuracy. Atomic data is based on IUPAC 2024 references and CODATA 2022 constants, with masses in unified atomic mass units (u).
- Modern, careful design. Every panel, animation and color was tuned to make complex chemistry feel approachable.
§ 03 What you'll find inside
- Periodic Table — Click any element to explore atomic mass, electron configuration, electronegativity, oxidation states, occurrence and real-world applications.
- Viewer — Historical and modern atomic models in WebGL. Interactive 3D is part of the public lab.
- 3D Molecules & Allotropes — Geometry of water, ammonia, methane and more. Open without an account.
- Calculators — Molar mass, dilution, scientific, units, gas and pH stay open. Reaction Workbench and thermo stay in Pro.
§ 04 Why we built this
Atomurus started as a personal project to make chemistry feel less like memorization and more like exploration. Most online tables and atomic viewers are either visually outdated, locked behind subscriptions or scattered across separate tools. Atomurus brings them together under one consistent design system, with attention to typography, color and animation that respects the science.
§ 05 Open by default
You do not need an account for the periodic table, element pages, Explore articles, 3D viewers or basic calculators. A free account saves your library, notes and Study Sets. Interactive solvers and study intelligence are Pro. Theme, element size and language stay in your browser.
§ 06 Built with
Atomurus is built with standard web technologies — HTML, CSS and JavaScript — using Three.js for 3D rendering and Chart.js for trend graphs. The site is statically hosted, so it loads fast anywhere in the world.
§ 07 Independence
Atomurus is an independent educational project. It is supported by non-intrusive advertising, which helps keep the site fully free and open for everyone. For more details on how data is handled, please see our Privacy Policy.
