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.

For the Lewis structure for SO3 2- you should take formal charges into account to find the best Lewis structure for the molecule. It will be necessary to create a double bond on the Oxygen (O) atom for the formal charges to work.

Also note that you should put the SO3 2- Lewis structure in brackets with as 2- on the outside to show that it is an ion with a negative two charge.
