WebExamples of Radius Ratio Rule. The ratio of radii of the ions can affect the arrangement of ions in a crystal. Moreover, the limiting ratio has to be greater than 0.414, (radius ratio greater than 0.414) to fit an octahedral arrangement of anions. In this formation, cations will be able to accommodate 6 anions. WebCalcium commonly forms a cation with a charge of +2 Bromine commonly forms an anion with a charge of -1 In the formula of an ionic compound we are showing the ratio between the ions. The overall charge of any ionic compound is 0 so for that to happen we need 2 bromide ions for every 1 calcium ion. So the formula is CaBr2
