To illustrate the structure of Lewis,P has 5 valence electronsO has 6 valence electrons (each 4 oxygen)And finally, for every negative charge, there is an additional valencia electronWe should add these all = 5 + 24 + 3 = 32 valencia electronsWith this, we can be guided to illustrate the structure of lewis as the P as the central atom and the 3 oxygen, each one with a single link with P and 1 of oxygen with a double bond with P. we place the valence electrons to the octet rule is met,we will be left with 12 pairs free to the phosphate ion.
