Tendencies of ionic/atomic radii in the periodic table
... Tendencies of ionic and atomic radii in the periodic table Tendencies: 1. The atomic radii increase down a group (e.g. first group 157 – 272 pm) and within the s and p blocks, decrease from left to right across a period (e.g. second period 157 – 64 pm). 2. The atomic radii for elements following the ...
