He, F, and H cannot serve as central atoms in a Lewis structure. pair on each O to a bonding pair on N. No resonance is required as all atoms. SF6 is nonpolar because it is octahedral, AX6, and the bonds are arranged so they cancel. B.
Jun 5, 2019. The Lewis structure helps us identify the bond pairs and the lone pairs. When the electron groups are all bond pairs, they are named exactly. Since water has two lone pairs it's molecular shape is bent. A molecule is polar when the electrons are not distributed equally and the molecule has two poles.
