Phosphate is critical to the functioning of both ATP and DNA. The stable form of phosphate in solution is the phosphate anion (a negative ion) PO43- This is a tetrahedral molecule, with a central P+ ion surrounded by four O ions. The P-O bond lengths are 0.14 nm, which corresponds to an O-O distance of the edge length of the tetrahedron of 0.24 nm. What is the electric potential energy of a phosphate anion? Show your work
