Periodex is a simple, responsive way to explore the periodic table of elements. We hope it provides a quick and enjoyable reference for students and enthusiasts.

Periodex has just began. We plan to add more features and information. If there’s a way that we can make it more valuable to you, please let us know!

To use Periodex, simply hover over an element to reveal addition information on the info panel on the right side. You can click on an element to lock the focus. Click again to unlock. You can toggle the info panel by clicking the info button on the top bar.

Periodex is designed to be flexible. Grab a corner and adjust the size to fit your needs.
