Question:

Draw out the Lewis dot structures for the sulfate ion, {eq}\rm SO_4^{2-} {/eq} and the phosphate ion, {eq}\rm PO_4^{3-} {/eq}, showing how they end up with the charges they have.

Lewis Structure

Lewis structures decide the formal charges on individual atoms, which add up to give overall molecular charge. More electronegative elements having negative charges impart stability to structure.
