Expert Answer:

We  dont  get to see diagonal relatonships between every two diagonal elements in the periodic table due to the fact that the mandatory factor for diagonal relationship is similar charge densities on the ions involved. 
 
For example, Li+ is a small cation with a +1 charge and Mg2+ is somewhat larger with a +2 charge, so the charge density on each ion is roughly the same. Using the Li–Mg pair ; but it is not the same after B & Si.
