In VSEPR theory, the position of bound atoms and lone pair electrons are described relative to a ___________ . Once the bound atoms and lone pair electrons are positioned, the resulting geometrical shape presented by the _________ (ignoring lone pairs) is used to describe the ______________ . The position of electron pair (bound and lone) is based on the idea that electron pairs on the central atom will repel from each other as far as possible. The VSEPR Model
