Question
In the crystals of ionic compounds, how do the relative sizes of the ions influence the location of the smaller ions? Please choose the answer that offers the best explanation. The relative sizes are irrelevant to the overall placement of the atoms, The larger ions squeeze the smaller ions into the interstitial voids. The ratio of the radii of the smaller ion to the larger ion determines whether the smaller ion Tills a tetrahedral hole (smallest), octahedral hole, or cubic hole (largest). The larger ions need to stay as far from each other as possible, forcing the smaller ions to be squeezed between two larger ions. The ratio of the radii of the smaller ion to the larger ion determines whether the smaller ion fills a hole or a lattice position.Explanation / Answer
A:- The ratio of the radii of the smaller ion to larger ion determined whether the smaller ion fills a tetrahedral hole (smallest), octahedral hole, or cubic hole (largest).
