Build a Molecule
How many different molecules can you build? In a simulation, learners make molecules from given atoms. There are numerous collections from which to build three to five molecules from given kits of atoms. Scholars can also view their...
PhET
Molecule Shapes: Basics
In molecules, bonds rotate about the nucleus due to the repulsion of subatomic particles. In a simulation, learners manipulate the bonds of a molecule to meet the atoms' needs. They can then see the specific molecular shapes of five...
PhET
Molecule Shapes
The shape of a molecule is determined by the arrangement of atoms around the central atom and lone pairs of electrons. Scholars build models of molecules using single, double, and triple bonds. They can then see real molecules bond...
