Interactive: Electron Geometry: Molecules assume different shapes due to patterns of shared and unshared electrons. One group has an unshared pair of electrons. How to Determine Electron Geometry. In NH3, as we have three hydrogens, all of them will be set around the central atom of nitrogen, and all the eight valence electrons are going to form chemical bonds with them. Contrast this with ammonia, NH3, which does have a lone pair. The hydrogen atoms are just S orbitals which will overlap with those SP3 orbitals, so that’s it. And this is the Lewis structure for NH3. The fourth hydrogen bonds to the ammonia molecule as a hydrogen ion (no electrons) bonding to the lone pair on the nitrogen. While the electron geometry is tetrahedral, the NH 3 molecular geometry is trigonal pyramidal. One group has an unshared pair of electrons.
