Document Summary
Chapter 10 chemical bonding i i: molecular shape, valence. Properties of molecules depend on structure of molecule (factors include skeletal arrangement of atoms, kind of bonding and shape of molecule) Molecule are 3-d objects (describe shape of molecule with terms that relate to geometric figures, which have characteristics corners that indicate position of surrounding atoms around central atoms, and bond angles) Vsepr theory: valence shell electron pair repulsion theory because electrons are negatively charged, they should be most stable when they are separated as far as possible. 5 basic arrangements of electron groups around a central atom (maximum 6 bonding electron groups, though there maybe > 6 on very large atoms but is rare) The actual geometry may be different from the different) geometry (due to electron groups being attached to different size, when bonding is electron. 10. 3 vsepr theory: the effect of lone pairs.
