Electrostatic potential maps use color to portray the calculated electron distribution in a molecule.Atoms that are electron poor and carry a δ+ charge are shown in blue.Atoms that are electron rich and carry a δ- charge are shown in red.Atoms with little or no charge are shown in green.The electrostatic potential map of H2O below should show
