Periodic Table
Interactive periodic table with live state changes, property heatmaps, and element comparisons.
About this periodic table
This tool covers all 118 known elements with live data — drag the temperature slider and watch which elements melt, boil, or stay solid at that exact temperature. Switch between grid and list views, filter by category or block, overlay a property heatmap, and pin up to three elements to the comparison tray to see their numbers side by side.
Search & filter
Find an element by name, symbol or atomic number, then narrow the grid by category or block.
Live states of matter
Move the temperature slider to see each element's phase update in real time, from absolute zero to 6000 K.
Compare & export
Pin elements to the comparison tray for a quick side-by-side, or export the full table to CSV.
Frequently asked questions
How is the state of matter calculated?
Each element's melting and boiling points are compared against the temperature you set, so the displayed state always reflects that exact temperature.
What do the heatmap colors mean?
Choosing a property like electronegativity or atomic mass shades every element on a gradient, so you can spot trends across periods and groups at a glance.
Can I compare more than three elements?
The comparison tray holds three at a time, keeping the side-by-side view easy to read. Remove one to pin a different element in its place.
