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.

🤓 Based on our data, we think this question is relevant for Professor TBA's class at MC.
