Problem

In Section 2.6 in the textbook we discussed the metalloids, which form a diagonal band separating the metals from the nonmetals. There are other instances in which elements such as lithium and magnesium that are diagonal to each other have comparable metallic character. Suggest an explanation for this observation.

Solution

We are asked to explain the existence of a comparable metallic character between lithium and magnesium

Recall diagonal relationship:

Diagonal relationship occurs when elements of the upper period show similarities in properties with the diagonally opposite elements of the lower period.

Take a look at Lithium and Magnesium:
