How to Determine Molecular Geometry – YouTube: This video describes one method for quickly finding the major geometrical shapes for simple molecules. We have 3 Bromines, and then we need to add in this negative up here, an additional valence electron, for a total of 22 valence electrons for the Br3- Lewis structure. Molecular geometry is a method to determine the shape of a molecule based on the repulsion occurring between bond electron pairs in the outermost (or valence) electron shell. Here is a similar molecule (theoretically): Iodine Trifluoride on Wikipedia. To make the long story short, I got this feeling that the answer was trigonal planar, the same as its molecular pair geometry. Determine the Electron Domain Geometry and Molecular Geometry. Remaining 4 electrons are present as 2 lone pairs. What is the electron pair geometry of xenon tetrachloride? geometry, or three-dimensional shape of a molecule or polyatomic ion, can be determined using valence-shell electron-pair repulsion (abbreviated VSEPR and pronounced “VES-per”) theory, in which the basic principle is valence electrons around a central atom stay as far apart as possible to The molecular geometry of Br 3 is T-shaped with an asymmetric charge distribution on the central atom.
