Beryllium has diagonal relationship with
Correct answer: D. Al
- A. Li
- B. B
- C. Na
- D. Al
Explanation
Beryllium exhibits a diagonal relationship with Aluminum due to the similarities in their chemical behaviors, particularly in their ionic sizes and electronegativity. This diagonal relationship is observed between elements diagonally adjacent in the periodic table where they have comparable properties despite being in different groups. Lithium, Boron, and Sodium do not share this diagonal relationship with Beryllium, with each differing significantly in their chemical properties and atomic configurations.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
