Recall that ionic radius is the size of an ion. The trend for ionic radius is as follows: it increases from right to left and down a period in the periodic table. Ionic radius also increases with increasing number of electrons.
The following ions contain the same number of electrons. Rank them in order of decreasing ionic radii.(Cs+, I-, La3+, Sb3-, Ba2+, Te2--)
Rank from largest to smallest radius. To rank items as equivalent, overlap them.
