SHAPES OF MOLECULES
WEBSHAPES OF MOLECULES. Molecules and ions possess two types of electron pairs: Bonding pairs (the two shared electrons in a covalent bond) Lone pairs (two electrons in a pair not involved in bonding – also known as non-bonding pairs). These electron pairs will repel each other as far as possible.
WEBThe molecular geometry, or three-dimensional shape of a molecule or polyatomic ion, can be determined using valence-shell electron-pair repulsion (abbreviated VSEPR and pronounced “VES-per”) theory, in which the basic principle is valence electrons around a central atom stay as far apart as possible to. minimize the repulsions.
