WebAn electron group can be an electron pair, a lone pair, a single unpaired electron, a double bond or a triple bond on the center atom. Using the VSEPR theory, the electron bond pairs and lone pairs on the center atom will help us predict the shape of a molecule. The shape of a molecule is determined by the location of the nuclei and its electrons. WebSep 21, 2024 · The molecular geometries of molecules change when the central atom has one or more lone pairs of electrons.
