PERIODIC TABLE

How can we help?

Explore an element

Tap a tile to open its properties, electron shells, valence, history, uses and selected isotopes. Move and zoom the table with gestures or its zoom buttons. Search accepts names, symbols and atomic numbers.

Change the language

Open About using the information icon. The language menu appears beside Licenses. English, Spanish, Arabic, French, Hindi, Thai and Russian are available offline.

Report a problem or a correction

Email ultim8digital@gmail.com with the app version, your device and operating-system version, and steps to reproduce the problem. For a scientific correction, include the element, field and a reliable reference. Do not include passwords or sensitive personal information.

About the data

Unknown properties are marked explicitly. Valence and oxidation state are different quantities; the examples and isotopes are a reference selection. Translations are machine-assisted and have received selective editorial review.
