WebSep 8, 2016 · The answers in this post suggests an exactly opposite outcome. All the answers says that M g X 2 + is above C a X 2 +, thus it has a smaller radius. By applying the exactly same logic i can say L i X + is above A l X 3 + so it must have less ionic radius but that is not the case. As the below picture suggests, (taken from the same post).
