AP EAMCET · Chemistry · Classification of Elements and Periodicity in Properties
The number of following pairs of elements which exhibit diagonal relationship is:
- A \(2\)
- B \(1\)
- C \(3\)
- D \(4\)
Answer & Solution
Correct Answer
(C) \(3\)
Step-by-step Solution
Detailed explanation
Diagonal relationship is exhibited by an element and the element lying diagonally right to the next group in the next period. \(\mathrm{Li} \rightarrow \mathrm{Mg}, \mathrm{Be} \rightarrow \mathrm{Al}, \mathrm{B} \rightarrow \mathrm{Si}\).
