Count valence electrons S = 6 3 x O = 3 x 6 = 18 Negative charge = 2 TOTAL = 6 + 18 + 2 = 26 e- or 13 pairs. Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. 1. Sulfite ion, SO32-Step 2. Being an ion, sulfite, like sulfide, has a negative charge. Unfortunately, this is one of the cases where the octet rule just doesn't apply. This addition causes the creation of bonds in the ion, another feature sulfide ions do not have. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom. Our findings suggest that, during the evolutionary development of hearing, there was a molecular switch between expression and use of the Tmc1/2 proteins. So, the conclusion is, SO2 is a Polar molecule. e) none of these orbital types.
