a phosphate group is a polyatomic ion which contains both ionic and covalent bonds. By definition, a phosphate group is PO4 with a charge of -3.

Is PO4 an ionic bond?

BRIAN M. Sodium Phosphate is an ionic compound formed by two ions, Sodium Na+ and Phosphate PO−34 . In order for these two polyatomic ions to bond the charges must be equal and opposite. This will make the formula for Sodium Phosphate Na3PO4 .

The overall charge on the phosphate ion is -3 and the phosphorus atom is in an oxidation state of +5. In the Lewis structure of PO43-, P forms single bonds with 3 oxygen atoms and forms a double bond with one oxygen atom.

Is PO4 2 ionic or covalent?

The name of the compound is beryllium phosphate. This is an ionic compound.
