Bonded and Lone Pairs in VSEPR
In the textbook, it says "The valence electrons contribute to the electron arrangement about the central atom, but only bonded atoms are considered in the identification of the shape". I thought that the lone pairs also contributed to naming the molecular geometry.

I think lone pairs are taken into account when determining the electron distribution shape, not the molecular shape. According to my TA, the molecular shape is usually. what professor Lavelle asks for on tests.

Re: Bonded and Lone Pairs in VSEPR
Lone pairs help when determining the general shape but when it comes to molecular shape lone Pairs only influence the shape through repulsion and therefore only bonded atoms effect shape.

Re: Bonded and Lone Pairs in VSEPR
Lone pairs DO influence molecular shape, but only atom positions are used to name the actual shape.
