A.It is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge distributed over the entire ion.
B.It is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge on the phosphorus atom.
C.It is composed of one phosphorus atom and four oxygen atoms ionically bonded together, and there is a –3 charge distributed over the entire ion.
D.It is composed of one phosphorus atom and four oxygen atoms ionically bonded together, and there is a –3 charge on the phosphorus atom.

A covalent bond is a bond in which electrons are shared. In an ionic bond, electrons are completely transferred. In this case phosphate ion (PO4)-3 is covalent which means that C and D cannot be the correct answer. Additionally, since the charge is on the oxygen atoms due to the bonding with phosphorus, we can say that the charge is on the entire ion and not just on the phosphorus atom. Therefore the answer is A.
the answer is A I believe
