Explore all 118 elements
The periodic table organises all known elements by their properties, and an interactive version makes exploring it far richer than a static chart. This tool presents an interactive periodic table of all 118 elements, and clicking any element shows its details, so you can learn chemistry by exploration.
Why the table is arranged as it is
The periodic table is not just a list; its layout encodes the elements’ properties. Elements in the same column share similar chemical behaviour because they have the same outer-electron structure, and properties trend predictably across rows and down columns. That is why the table’s shape matters, and why an interactive version, where you can click into an element and see how it relates to its neighbours, teaches the underlying patterns better than memorising isolated facts.

Frequently Asked Questions
What does the interactive table show?
All 118 elements arranged by their properties, with the details of any element shown when you click it, for learning by exploration.
Why is the table arranged the way it is?
Because the layout encodes properties: elements in the same column share similar chemical behaviour, and properties trend predictably across rows and down columns.
What can I learn from it?
Each element’s properties and how it relates to its neighbours, which teaches the periodic patterns that underlie chemistry.
Who is it for?
Students learning chemistry, teachers, and anyone curious about the elements and how the periodic table organises them.
Is my input uploaded?
No. The table runs entirely in your browser.
