The Metaphosphate Ion, PO₃^-, Is the Structural Analog of the NO₃^-

The metaphosphate ion, PO₃^-, is the structural analog of the NO₃^- ion with respect to the arrangement of the atoms in the ion. After drawing the "best"Lewis structure for the metaphosphate ion based on formal charge considerations, what is the formal charge on the phosphorus atom? Hint: Do not forget about double or triple bonds potentially being in the Lewis structure.

A) 1-
B) 0
C) 1+
D) 2+
E) 5+
