University of Colorado: Ph Et Interactive Simulations: Molecule Shapes

For Students 9th - 10th
Build a molecule in 3-D. Add single, double, and triple bonds, or a lone pair of electrons to an atom, learn what the molecule's geometric name is, see the bond angles, and manipulate each molecule to view it from all sides. Then study a...
