    Here are some points regarding ion sizes:

    * anions are larger than parent atoms
    * cations are smaller than parent atoms
    * atom size increases going down family (down a column in the periodic table). ion size also increases.

    Thus the order is (from smaller to larger):
    Ti < Sc < Ca < ...

    Solution Summary

    The solution explains why anions and cations have such huge difference in their size.
