A reference that never needs the internet

The full dataset, atomic masses (2021 IUPAC standard values; bracketed mass numbers for elements with no stable isotope), shorthand electron configurations, Pauling electronegativities where defined, phases at standard conditions and discovery years, is embedded right in this page. Color the table by category, phase or s/p/d/f block, search by name, symbol or number, and copy any element's summary or download the whole dataset as JSON or CSV. No account, no upload, works offline. Free forever.

§ 04 · faq

Frequently asked questions.

Is the Periodic Table free?
Yes, completely free for everyone. No sign-up, no account and no usage limits.
Is it private? Is anything uploaded?
No upload, ever. The element data is embedded in the page and all searching, coloring and rendering happens in your browser on your own device.
Does it work offline?
Yes, once the page has loaded, everything keeps working without a connection, because the full dataset and all logic live in the page itself.
Where does the element data come from?
Atomic masses follow the 2021 IUPAC standard values, with bracketed mass numbers for elements that have no stable isotope. Electronegativities are Pauling values where defined, and electron configurations use the standard shorthand notation.
Can I export the data?
Yes, download the complete 118-element dataset as JSON or CSV with one click, or copy any single element's summary as plain text.
