WebVSEPR Theory. Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure. The VSEPR model assumes that electron pairs in the valence shell of a … http://www2.chem.wisc.edu/deptfiles/genchem/netorial/rottosen/tutorial/modules/intermolecular_forces/01review/review2.htm

For example, in PCl3, chlorine is more electronegative than phosphorus, occupy the terminal position and phosphorus is the central atom. Hydrogen is an exception as can NEVER be the central atom. The atom with the lowest subscript in the … WebOct 27, 2024 · The atom with the lowest ionization energy is typically the central atom. Hydrogen is never the central atom because it can only form one single bond. When drawing Lewis structures, you have to put into consideration what the electronegativity trend is the elements that are present, either by itself or in a chemical compound. flapjack made with oil
