Thus, the ion will be polar unless the Lewis structure (electron dot structure) is symmetrical. I hope this article made sense to you and helped you to understand BF3 Lewis Structure, Molecular Geometry, Hybridization, and Polarity. Iodine is the least electronegative, so we'll put it in the center, and then we'll put our Fluorines on the outside. The two reactions are:. Trifluoro-lambda~3~-iodane. First of all, a correct count of all valence electrons is essential. First you must have a Lewis structure that shows all the lone pairs (nonbonding electrons). Since oxygen is more electronegative then nitrogen, the negative charge is more stable when its on the oxygen atom. From the Lewis structures (see Exercise 8.
