Question

Diagonal relationship is shown by the elements.
a) Be and Mg
b) Li and Mg
c) Li and Na
d) Be and Ba

Answer 1

Answer:

Li and mg so this is the answer for the question

Answer 2

Answer: the answer is lithium and magnesium

Explanation:  

the elements Lithium and magnesium have small size as they are first in the row of periodic table and high charge density. The electronegativities of Li is 1.0 and Mg is 1.2. They are low and almost same. Their ionic radii are similar. Hence they show similarities which is known as diagonal relationship between first element of a group with the second element in the next higher group.
