An example of a stable molecule with an odd number of valence electrons would be nitric oxide. The attraction of each atom's nucleus for the valence electrons of the other atom pulls the atoms together. Now there is a charge of -3 on the whole atom which means there are 3 additional valence electrons present. Thus SF6 has 48 valence electrons that will help us draw the Lewis Dot Structure of SF6. SF6 Lewis Structure. Feb 15, 2023 · When atomic orbitals hybridize, the valence electrons occupy the newly created orbitals. There are 5xx6+2=32 "valence electrons", distributed around 5 centres. Notice that this gives a total of five electron pairs.
