VALENCE-SHELL ELECTRON-PAIR REPULSION MODEL ( VSEPR ) Basic Steps for Using the VSEPR Model h Draw the Lewis structure for the molecule. h Count the electron pairs* (bonding pair or lone pairs) around the central atom and arrange them in the way that minimizes repulsions, that is, put the pairs as far apart as possible . h Determine the positions of the atoms. h Name the molecular structure from the positions of the atoms . *Steric number

LONE PAIR ELECTRONS ARE BULKIER THAN BONDING PAIRS OF ELECTRONS In a bonding pair of electrons the electrons are shared by two nuclei In a lone pair, since both electrons must be close to a single nucleus, they tend to take up more of the space around that atom.
