The atomic radii of a divalent cation and a monovalent anion are 0.054 nm and 0.143 nm, respectively. (a) Calculate the force of attraction between these two ions at their equilibrium interionic separation (i.e., when the ions just touch one another). i (b) What is the force of repulsion at this same separation distance?
