Ionic Radius is the distance between an ion's nucleus and its most outer occupied electron shell.
Ionic Radius
Concept #1: Ionic Radius
Periodic Trend: Ionic Radius increases as the number of electrons increases.
Example #1: Which of the following statements is false?
Example #2: Arrange the atoms and/or ions in order of decreasing ionic radius: Fe2+, Mn+, Ni2+, Zn2+.
Practice: For an isoelectronic series of ions, the ion that is the smallest is always
