The VSEPR model can predict the structure of nearly any molecule or polyatomic ion in which the central atom is a nonmetal, as well as the structures of many molecules and polyatomic ions with a central metal atom. The Lewis electron structure is. Because electrons repel each other electrostatically, the most stable arrangement of electron groups (i.e., the one with the lowest energy) is the one that minimizes repulsions. The sigma bond is short and strong. To minimize repulsions the three groups are initially placed at 120 angles from each other. Moreover, experimental evidence says that at the ground state it possesses 2 unpaired electrons in its 2p orbitals. With five bonding pairs and one lone pair, BrF5 is designated as AX5E; it has a total of six electron pairs. Structure (b), with fewer LPBP repulsions at 90 than (a), is lower in energy.
