Question
The behaviour of lithium is similar to that of
magnesium. This sort of similarity is commonly referred to as:Solution
The behavior where lithium (an alkali metal) shows similarities with magnesium (an alkaline earth metal) despite being in different groups of the periodic table is referred to as a " diagonal relationship" in the periodic table. This phenomenon is observed in the second period elements where they show similarities with the elements diagonally located in the third period.
