Answers (1)

The reason for the anomalous diagonal relationship between boron and silicon is that they have similar atomic radii despite being in different periods of the periodic table. This is due to a balance between the increasing nuclear charge and the screening effect of the electrons in the inner shells. As a result, boron and silicon have similar chemical and physical properties such as high melting and boiling points, covalent bonding, and the ability to form complex compounds.
