WebbThe shape of a molecule is determined by the location of the nuclei and its electrons. The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction. Thus, the molecule's shape reflects … WebbThe shape of a molecule can be predicted based on the number and arrangement of electron pairs around a central atom. The geometry is determined by minimizing the repulsions between electron pairs in the bonds between atoms and/or lone pairs of electrons as postulated by VSEPR theory. How do valence electrons influence shape?
