WebAs described by the VSEPR model, the five valence electron pairs on the central atom form a trigonal bipyramid in which the three lone pairs occupy the less crowded equatorial positions and the two bonded atoms occupy the two axial positions at the opposite ends of an axis, forming a linear molecule. See also [ edit] AXE method Molecular geometry WebVSEPR is short for "Valence Shell Electron Pair Repulsion," a chemical theory originally developed by R. Gillespie and R. Nyholm for forecasting the shapes of molecules based on the amount of electron pairs circling a central atom. A VSEPR Chart PDF version can be downloaded through the link below.
