The element exhibits resonance (4 times) as there is a double bond with 1 oxygen and a single with the other 3 oxygen. This switches in each resonance structure. (I know its weird b/c I leaves Phosphorus with 10 electrons surrounding it)

The central phosphorus atom has 8 bonding electrons and 0 lone pair electrons for a total of 8+ 0 = 8 electrons in its valence shell.

Since the total number of electrons around P is equal to 8, the octet rule is obeyed.

The Lewis dot structure of phosphate (PO4^3-) is drawn by the following procedure. Place a P atom in the center. Single bond this P atom to 3 separate O atoms. place a - sign by each O atom. Double bond the P to one more O atom.
