Drawing Lewis Structures Count valence electron

Drawing Lewis Structures Count valence electron Place least electronegative in center

Drawing Lewis Structures Count valence electron Place least electronegative in center Draw dashes to form bonds

Drawing Lewis Structures Count valence electron Place least electronegative in center Draw dashes to form bonds Fill valence on outer atoms

Drawing Lewis Structures Count valence electron Place least electronegative in center Draw dashes to form bonds Fill valence on outer atoms Make sure center atom has octet

Drawing Lewis Structures Count valence electron Place least electronegative in center Draw dashes to form bonds Fill valence on outer atoms Make sure center atom has octet Form double or triple bonds if needed

Note: a nonbonding pair of electrons acts like a regular bond but takes up more room.

All bonds and lone pairs want to maximize their distance from each other
