Current Attempt in Progress Incorrect. The atomic radii of a divalent cation and a monovalent anion are 0.29 nm and 0.144 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 2.53E-9 N (b) What is the force of repulsion at this same separation distance? i -2.53E-9 N e Textbook and Media Hint Save for Later Attempts: 1 of 5 used Submit
