Click and drag the molecle to rotate it. The molecular geometry of PCl3 is trigonal pyramidal with asymmetric charge distribution on the central atom. Therefore this molecule is polar.

A step-by-step explanation of how to draw the SO3 2- Lewis Structure (Sulfite Ion). For the SO3 2- Lewis structure the total number of valence electrons (found on the periodic table) for the SO3 2- molecule. Once we know how many valence electrons there are in SO3 2- we can distribute them around the central atom with the goal of filling the outer shells of each atom.
