A step-by-step explanation of how to draw the PO4 3- Lewis Structure (Phosphate Ion). For the PO4 3- Lewis structure use the periodic table to find the total number of valence electrons for the PO4 3- molecule.Once we know how many valence electrons there are in PO4 3- we can distribute them around the central atom with the goal of filling the outer shells of each atom.In the Lewis structure of PO43- there are a total of 32 valence electrons.For the Lewis structure for PO4 3- you should take formal charges into account to find the best Lewis structure for the molecule.Remember, PO4 3- has a negative three charge on the molecule.nce we know how many valence electrons there are in PO4 3- we can distribute them around the central atom with the goal of filling the outer shells of each atom. In the Lewis structure of PO43- there are a total of 32 valence electrons.
