Diagonal relationship is not shown by (BHU 2008)
A.Li and Mg
B.Be and Al
C.B and Si
D.C and P✓ Correct
Explanation
Light elements of second-period shows resemble the properties with the next group of elements in the third period. This resembles is due to the similar electronegativity of elements and the diagonal pairs are Lithium (Li) and Magnesium (Mg), Beryllium (Be) and Aluminum (Al), Boron (B), and Silicon (Si). Therefore, the correct option is d. Electronegativity increases Electronegativity decreases
