Answer: In the ionic salt KF, the separation distance
Chapter , Problem 64(choose chapter or problem)
In the ionic salt KF, the separation distance between ions isabout 0.27 nm. (a) Estimate the electrostatic potentialenergy between the ions assuming them to be point charges(magnitude le ). (b) When F grabs an electron, it releases3.41 eV of energy, whereas 4.34 eV is required to ionize K.Find the binding energy of KF relative to free K and F atoms,neglecting the energy of repulsion.
