Once we know how many valence electrons there are in PO3 3- we can distribute them around the central atom and attempt to fill the outer shells of each atom. Draw a single lewis structure for the phosphate ion (po43-), assuming that the phosphorus atom can expand its octet such that the formal charge on each of the atoms is minimized. Electrons. Chemistry pretty urgent!!!!! b) molecular geometry. Valence: Here, sulfur in the center because of its lowest electron capability, and three oxygen around it. Lewis structure is based on the octet rule. So those are our valence electrons. VSEPR theory. PO4 3- Lewis Structure: How to Draw the Lewis Structure for PO43-x. Is PO4(3-) polar or non-polar? Oxygen has 6, we've got 4 Oxygens. In the Lewis structure of PO43- there are a total of 32 valence electrons. But all of the bonds in PO4^3- are identical. CHEMISTRY 101: Drawing Lewis Structures, Resonance and Formal charge for Phosphate In this example problem, we draw the Lewis structure for phosphate which minimizes formal charge; there are multiple resonance structures. Therefore, the only way to represent this with Lewis … check_circle Expert Answer. ClO3-Which of the following is/are possible Lewis structures for C2H6O?
