A popular tool to study molecular geometry in school is the molecular model kit. Many such kits are available, such as the two shown below. We created an online tool with a very similar experience. You can put together molecular structures from basic building blocks using pre-defined VSEPR geometries. Try it for free on builder.molview.org!
This tool is a proof-of-concept. There are many interesting new features possible, such as rotating atoms, different bond types, orbitals, cyclic structures, and automatic geometry correction. We invite you to try our tool and send your ideas to builder@molview.org.
