The size of an atom or ion is dependent upon its position in the periodic table. Properties such as the ionic radius are called periodic trends because they vary as we move along a period or a group.
Ionic radius decreases as we move up a group. This is because the number of energy levels (or shells) decreases as we move up a group.
Rank the following ions in order of decreasing radius: O2-,S2-,Se2-,Te2-, and Po2-?.
