Interactive periodic table with atomic, chemical and physical properties of all known elements. Element lists, scales and much more free, free and open source.
The project consists of several phases, which will gradually add more functions to pse-info.de. These will include the nuclide map, calculation tools and much more. It is also planned to implement an interactive periodic table.
Whole rework of data and source code for the pse-info.de project. New features, extended content, support for multiple languages, light and dark theme and much more.
Integration of the more than 3,000 known nuclides incl. interactive nuclide table, important information, decay chains, etc.
Phase three provides the periodic table with a variety of important tools for calculations based on existing data, such as the molar mass of certain formulas, the radioactivity of nuclides, and many other things.
The PSE project is open source. This also applies to the data used on this website. These are provided under the MIT license and can be downloaded as needed.
The data provided on this website do not claim to be correct, complete and up-to-date. They come from reference books, Wikipedia, WebElements and other websites. Pse-info.de assumes no liability for the use of this data and points out to use further sources if necessary.
Like this website, its data can also be used freely. Feel free to use it to start your own project, perform further data analysis or similar. A reference to pse-info.de and the developer is not necessary, but it would be friendly and would help to increase the reach of the project.
Atomic, physical, etc. properties of all chemical elements.
Spectral lines of all chemical elements in base64 format.
Any liability for incorrect, erroneous or incomplete information is excluded. Provided data does not claim to be correct, complete and up-to-date. Pse-info.de does not replace the use of official tables and points out to consult additional sources if necessary. The use of pse-info.de is expressly intended only for general information and does not replace official sources.
In particular, the indication of toxicological data and the hazard labeling of chemical elements serve a purely informational purpose. The use of legal notices for handling such substances is generally recommended.
