About Interactive Periodic Table
We built this free educational resource to make the periodic table easier to explore, understand, and use—from a first chemistry lesson to a quick reference for any of the 118 elements.
Clear and useful
Scientific information is presented in approachable language for students, teachers, and curious learners.
Transparent and correctable
We explain how the data is prepared and provide a direct way to report an error or suggest an improvement.
Our mission
Make chemistry approachable without oversimplifying it
Interactive Periodic Table combines a complete element reference with visual exploration and practical learning tools. Visitors can search and filter the table, open detailed element profiles, study periodic trends, test their knowledge, and experiment with real compounds in the Alchemy Sandbox.
The project is intended for students, teachers, families, and science enthusiasts worldwide. It is designed to work well on desktop, tablet, and mobile devices and to remain useful without requiring registration.
Data and sources
How the element information is prepared
The site combines curated educational explanations with a structured physical-property reference table. Data is normalized into consistent fields and units before it is used across the interactive table and the 118 element pages.
IUPAC Periodic Table
Reference for official element names, symbols, atomic numbers, and the organization of the modern periodic table.
PubChem
Public scientific reference used when checking physical and chemical properties of the elements.
Los Alamos National Laboratory
Reference material for element properties, discovery history, and supporting scientific context.
Scientific values can vary with isotope, allotrope, temperature, pressure, and measurement method. Some properties of short-lived superheavy elements are predicted or remain unknown. Where appropriate, the site uses rounded reference values and avoids implying greater certainty than the sources support.
Editorial approach
Accuracy, context, and corrections
- Element names, symbols, atomic numbers, categories, and units are checked for internal consistency.
- Physical-property values are stored with their units and may be rounded for readability.
- Predicted, unavailable, or uncertain values—especially for superheavy elements—are not presented as precise measurements.
- Educational explanations are written to add context rather than simply reproduce reference tables.
- Corrections are reviewed and incorporated when a reliable source supports the change.
