Question
Which of the following pairs of elements exhibits a strong Diagonal Relationship, resulting in virtually identical polarizing power and electronegativity?
Answer: B
💡 Solution & Explanation
The classic diagonal pairs in the 2nd and 3rd periods are $Li-Mg$, $Be-Al$, and $B-Si$. Moving diagonally cancels the opposing period and group trends, keeping the ionic potential (charge/size ratio) constant.
