Ionic radius of boron ion
Web8 jan. 2024 · The atomic radius i.e., the metallic radius of gallium ( 135 p m) is less than that of aluminium ( 143 p m ). My book provides the following reason: It is due to the presence of additional 10 d-electrons in gallium which offer poor screening effect for the outer electrons from the increased nuclear charge. http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch7/ie_ea.php
