WebIonic Radius Periodic Table. As an example, Potassium radius = 243pm. The radius of the potassium ion is 138pm. Isoelectronic entities are atoms and ions that contain an identical number of electrons. For example, both O2- and Mg2+ have ten electrons, yet they do not have the same ionic radius since their effective nuclear charge is different. WebIonic radius Ions are particles in the same way as atoms only they carry an electrical charge. This is due to the number of electrons in the outer shells. If a particle has one fewer electrons then it carries a positive charge (there is an excess of protons in the nucleus).
