We present measurements of the net electrical surface charge of silicon dioxide (SiO2) in contact with solvents of dielectric constants between 5 and … There is a lone pair of electrons on S as well as three bonds (the bond to O is a double bond). Thus, water is a polar molecule (μ > 0). Re: SiO2. Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. Polarity comes from due to difference of electronegetivity and unequal sharing of valance electrons in a compound. Give the following information for a molecule of SiO 2? (1) Cl2 (2) SO3 (3) SiO2 (4) CCl4. The more electronegative an element is, the more the shared electrons will spend around that atom.
