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.
