The Iconic Periodic Table
The periodic table is chemistry's most recognizable image. Every student learns it. Every lab has one on the wall.
But it's always been static—a reference chart, not an interactive tool.
Our Design Philosophy
When designing CompoundLookup, we asked: What if the periodic table was a search interface?
The result: - Clickable elements - Each element is a button - Visual selection - Selected elements highlight clearly - Familiar layout - Standard periodic table arrangement - Color coding - Element categories are instantly visible
Design Decisions
Why Limit to 5 Elements? Most compounds contain 2-4 elements. Allowing 5 covers 99% of use cases while keeping the interface clean.
Why Color by Category? Element categories (metals, nonmetals, halogens, etc.) affect bonding behavior. Color helps users understand which elements they're combining.
Why Show Selection Bar? The top bar shows exactly what's selected, with one-click removal. No confusion about current search state.
User Feedback
Users consistently tell us the interface feels natural:
"I just clicked what I wanted and it worked"
"Way more intuitive than typing formulas"
"My students immediately understood how to use it"
The Periodic Table's New Purpose
We didn't replace the periodic table—we gave it a new job. It's still a reference for element properties. But now it's also a gateway to compound discovery.
Click, explore, learn. That's the CompoundLookup way.
