Ranking Ionic Radii for the elements begins with first counting their total number of electrons. 

Ranking Ionic Radii

Concept #1: Ranking Ionic Radii

Practice: Arrange the following atoms and/or ions in the order of increasing size: Br –, Kr, Rb+, Sr2+.

Practice: Arrange the following isoelectronic series in order of decreasing radius: F, O2–, Mg2+, Na+.

Practice: For an isoelectronic series of ions, the ion that is the smallest is always
