WebQuestion: Calculate the radius ratio for CaO if the ionic radii of Ca2 and O2– are 100 pm and 140 pm, respectively. Based on the radius ratio above, what is the expected coordination number of CaO? The range of radius ratios for each coordination number is given in parentheses. WebIonic radii are difficult to measure with any degree of certainty, and vary according to the environment of the ion. For example, it matters what the co-ordination of the ion is (how many oppositely charged ions are touching it), and what those ions are. cuddledry baby bath towelWebSolution. The correct option is C P 3− > S2− > Cl− > K+ > Ca2+. For isoelectronic species, as nuclear charge increases radius decreases. Greater the positive charge, lesser the size of ion.
