VSEPR Model

[Drew Hummer-Disc 1H]

I know that different atoms have different electronegativities as well as different radii which can affect the shape and charge of molecules. However, do differences in radius and size affect the VSEPR Model? Does the VSEPR Model even take into account differences in atomic radius?

Vsepr modeling assumes that you have the same atoms bonded to the "base" atom in the center. If you have differently sized atoms, then the Vsepr model will be slightly different. For example, if you have one larger element bonded to the base atom, then the other bonding sites will be pushed slightly further away due to the larger electron cloud that the atom possesses.
