THE INTERACTIVE CHEMISTRY LAB
Build your next
molecule.
Explore the elements, experiment with atom counts, and discover what chemistry can tell you about the combinations you create.
Start exploringYOUR WORKSPACE
Element explorer
Choose elements or enter a composition to see what we know.
Element builder
Define a composition, one element at a time.
Atom counts describe a proposed composition; they do not guarantee a stable compound or a chemical reaction.
Combination results
Your composition, interpreted carefully.
Ready when you are
Add elements to your builder and explore a composition to see its formula, mass, and any verified database match.

A PLACE TO BEGIN
Explore examples
Try a known composition. These educational examples are not preparation instructions.
CHEMISTRY, WITH CONTEXT
A composition is a starting point.
Matching atom counts can identify a known formula, but they cannot prove that a substance forms or that a reaction is practical. This explorer distinguishes verified educational examples from proposed compositions—and keeps the science honest.
