Aurum: Periodic Table Offline

Discover the elements without interruptions.

Aurum Periodic Tabel brings an interactive periodic table, detailed element references, chemistry tools and visual learning into one app. Study for class, check a property or explore the science behind matter at your own pace.

Absolutely no ads. No banner ads, pop-ups, video ads or rewarded ads. You never have to watch an advertisement to use a feature or earn simulation credits.

EXPLORE ALL 118 ELEMENTS

Browse the periodic table, zoom and pan, or search by name, symbol and atomic number. Save favourite elements and return to recently explored entries.

GO BEYOND THE SYMBOL
Explore atomic structure, electron configurations, isotopes, physical and chemical properties, spectra and crystal structures where data is available. Source links, measurement conditions and scientific qualifications help explain what each value means. Unknown or predicted values are identified rather than presented as established measurements.

20 CHEMISTRY CALCULATORS
Work with tools for molar mass, chemical equations, gases, solutions and other chemistry calculations. Supported tools include units, input validation and explanations to help you follow the result.

13 INTERACTIVE SIMULATIONS
Investigate atoms, Bohr-model energy levels, states of matter, nuclear fission, emission spectra, acid-base behaviour, periodic trends, the photoelectric effect, Brownian motion, Rutherford scattering, crystal structures, equation balancing and atomic interactions. Adjust controls and see how the model responds. Built-in help explains the concepts, equations, assumptions and limits.

LEARN THROUGH PRACTICE
Build familiarity with element names, symbols and atomic numbers through quizzes and custom practice selections. Review your results and copy practice history as CSV for your own records.

USEFUL REFERENCE MATERIAL
Explore chemistry reference tables, molecular structure diagrams, spectral information and scientific source material alongside the periodic table.

MADE FOR FOCUSED STUDY
Choose light or dark appearance, adjust text size and study in one of 25 supported languages. Core reference, calculator and learning features work offline. Study preferences, favourites and practice results are stored locally on your device. No app account is required for core educational features.

SIMULATION CREDITS AND OPTIONAL SUBSCRIPTIONS
Receive 5 free simulation credits each month. One credit opens a full simulation session; adjusting controls, using Help, pausing and resetting within that session do not spend another credit. All 13 simulations share one balance.

The current preview build uses test subscriptions and does not process real payments.

Three app-wide subscription options are available to preview: Basic, Pro and Unlimited. Availability, billing periods and applicable prices are shown in the app before purchase. Subscriptions are optional. The app has no ads at any subscription level.

Scientific simulations are educational models with stated assumptions and limitations. They are not substitutes for laboratory measurements or professional safety guidance. External source links and connected purchase services require internet access.
