WebIonic Radii. Ionic radius is the measure used to describe the size of an ion. A cation always has fewer electrons and the same number of protons as the parent atom; thus, it is smaller than the atom from which it is derived ().For example, the radius of a neutral aluminum atom (1s 2 2s 2 2p 6 3s 2 3p 1) is 118 pm, whereas the ionic radius of an Al … WebFor Sc 3+, the ionic radius is smaller than the one of Ca 2+ , so a higher complexation is expected.
