The Windows 10 periodic table of elements app Periodica has been open-sourced on GitHub three days ago. The source code of the project can now be found at https://github.com/Bluegrams/Periodica, where further development can take place and where you can open issues and feature requests. Most importantly, the app continues to be available for download via the Microsoft Store for free and without ads.

Periodica is a modern Periodic Table of Elements App for Windows 10. It provides comprehensive information about all chemical elements. Click on an element on the overview page to get detailed information about an element’s properties. Use the list view to sort and filter elements and get a quick overview of important properties. Or change the coloring mode to color the periodic table by category, block or state. Periodica was developed on the Windows 10 UWP platform and is freely available for download since 2018.
