What Determines the Basic Concepts
Shape of a Molecule? of Chemical

• The bond angles and bond Bonding
lengths determine the shape
and size of molecules.

• Electron pairs repel
each other.

• Electron pairs are as far apart
as possible; this allows
predicting the shape of the
molecule.

• This is the valence-shell
electron-pair repulsion
(VSEPR) model.
