VSEPR
VSEPR model - valence-shell electron-pair repulsion model
- bond angles - determines shape of molecules
- electron domain - area where electrons are most commonly found
- bonding pair - electrons between 2 atoms in bonds
- nonbonding pair - lone pair of electrons not shared
- nonbonding pairs, multiple bonds have greater repulsive forces on nearby electron domains than single bonds
- best arrangement minimizes repulsions between electron domains
- electron-domain geometry - determines arrangement of electron domains
- molecular geometry - determines arrangement of atoms
- atoms beyond 3rd period can have over 4 pairs of electrons around it (has extra d subshell)
