WebFeb 6, 2024 · The ionic radius of the elements exhibits trends in the periodic table. In general: Ionic radius increases as you move from top to bottom on the periodic table. Ionic radius decreases as you move across the periodic table, from left to right. WebThere are many exceptions to the trend. Careful examination will show that there is a sudden drop in ionization energy for members of the Boron Group (Group 13) compared to the previous element. That is because Group 13 is where the elements switch from filling s or back-filling d orbitals to filling p orbitals.
