About Easy Periodic Table

Explore all 118 elements, see how each atom is built, practise with quizzes, and print a table for your wall or classroom. Everything works in both languages, and you can switch at any time.

Easy Periodic Table is free to use. It has no accounts and no advertising, and your progress stays on your device (see Privacy).

Easy Periodic Table is an independent project. Its scientific values come from the sources below, and every value in the dataset cites one of them. Bengali text is checked by a chemistry teacher before it is marked as reviewed; until then, it is labelled as a draft.

Element data, isotopes and spectra come from these sources, under these licences.
