Key Takeaways: Ionic Radius Trend on Periodic Table The ionic radius is half the distance between atomic ions in a crystal lattice. To find the value, ions are treated as if they were hard spheres. The size of an element's ionic radius follows a predictabletrendon the periodic table. ...
Bothatomic radius and ionic radiusfollow a trend on the periodic table. The radius increases as you move down a group (column) and decreases as you move from left to right across a period (row). 3.Which of these elements has the highest first ionization energy?
