elementari
is a toolkit for building interactive web UIs for materials science: periodic tables, 3d crystal structures (and molecules, though needs some improvements!), Bohr atoms, nuclei, heatmaps, scatter plots. It's under active development and not yet ready for production use but we appreciate any feedback from beta testers! ๐
This screenshot demonstrates the periodicity of elemental properties (i.e. why it's called periodic table). In this case, you're seeing recurring bumps and valleys in the first ionization energy as a function of atomic number.
The details page for gold.

npm install --dev elementari
Import the PeriodicTable
component and pass it some heatmap values:
<script>
import PeriodicTable from 'elementari'
const heatmap_values = { H: 10, He: 4, Li: 8, Fe: 3, O: 24 }
</script>
<PeriodicTable {heatmap_values} />
PeriodicTable.svelte
forwards the following events from each ElementTile
:
click
mouseenter
mouseleave
keyup
keydown
Each event is a Svelte dispatch
event with the following detail
payload:
detail: {
element: ChemicalElement
active: boolean // whether the event target tile is currently active
dom_event: Event // the DOM event that triggered the Svelte dispatch
}

and PeriodicTableEvents

- Element properties in
src/lib/element-data.ts
were combined fromBowserinator/Periodic-Table-JSON
under Creative Commons license androbertwb/Periodic Table of Elements.csv
(unlicensed). - Thanks to Images of Elements for providing photos of elemental crystals and glowing excited gases.
- Thanks to @kadinzhang and their Periodicity project [code] for the idea to display animated Bohr model atoms and inset a scatter plot into the periodic table to visualize the periodic nature of elemental properties.
- Big thanks to all sources of element images. See

. - Thanks to @ixxie (shenhav.fyi) for a lot of great suggestions, UX ideas, helping me learn
threlte
and contributing theBond.svelte
component.
