$\text{HINT: Na and Mg are bridge elements.}$ $\text{Explanation:}$ $\text{Na and Mg are linked to Group IA and IB, and they are forming a bridge with}$ $\text{the elements which are placed diagonally opposite to Na and Mg, and the}$ $\text{properties of both the elements are similar due to electronegativity.}$ $\text{Bridge elements are those elements that show similarities in properties with}$ $\text{elements that are diagonally placed in the periodic table. This phenomenon}$ $\text{is known as the diagonal relationship.}$ $\text{Examples of diagonal relationships:}$ $\text{- Li (Group 1, Period 2) and Mg (Group 2, Period 3)}$ $\text{- Be (Group 2, Period 2) and Al (Group 13, Period 3)}$ $\text{- B (Group 13, Period 2) and Si (Group 14, Period 3)}$ $\text{The reason for diagonal relationship is that as we move across a period,}$ $\text{the charge on the cation increases and size decreases. As we move down}$ $\text{a group, the charge remains the same but size increases. The diagonal}$ $\text{movement combines both effects, resulting in similar charge-to-size ratios}$ $\text{and hence similar properties.}$ $\text{Among the given options, Mg is a bridge element as it shows diagonal}$ $\text{relationship with Li and forms a bridge between Group 1 and Group 2}$ $\text{elements.}$
