As the positive charge increases on metal cation, radius decreases. This is due to the fact that nuclear charge in the case of a cation is acting on lesser number of electrons and pulls them closer.

Isoelectronic Species and Ionic Radius
Isoelectronic species are atoms or ions that have the same number of electrons, but different numbers of protons. The ionic radius is the distance between the nucleus and the outermost electron of an ion.
Greater the Positive Charge, Smaller the Ionic Radius
- The ionic radius of a cation is determined by its positive charge.
- Amongst isoelectronic species, the smaller the positive charge on the cation, the larger is the ionic radius.
- This is because a cation with a smaller positive charge has fewer protons attracting the electrons, so they are held less tightly and are further away from the nucleus, resulting in a larger ionic radius.
Greater the Negative Charge, Larger the Ionic Radius
- The ionic radius of an anion is determined by its negative charge.
- Amongst isoelectronic species, the greater the negative charge on the anion, the larger is the ionic radius.
- This is because an anion with a greater negative charge has more electrons than protons, so they are held more tightly and are closer to the nucleus, resulting in a smaller ionic radius.
Atomic Radius of Elements in the Periodic Table
- The atomic radius of elements generally decreases as one moves across a period from left to right.
- This is due to the increasing nuclear charge, which attracts the electrons more strongly and pulls them closer to the nucleus, resulting in a smaller atomic radius.
- However, there are exceptions in some cases, such as the jump in atomic radius between the second and third periods due to the addition of a new energy level.
- The atomic radius of elements generally increases as one moves down a group in the periodic table.
- This is due to the increasing number of energy levels as one moves down a group, which results in electrons being further away from the nucleus and a larger atomic radius.
