Interactive simulation: Molecule Shapes

Explore molecule shapes by building molecules in 3D!

How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare the model to real molecules!
