Question:

$\text{Lithium shows a diagonal relationship with :}$

Options:

1. $\text{Sodium}$
2. $\text{Magnesium}$
3. $\text{Calcium}$
4. $\text{Aluminium}$

Solution:

$\text{Hint: Li is diagonally related to Mg.}$ $\text{Explanation:}$ $\text{A diagonal relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods (first 20 elements) of the periodic table.}$ $\text{These pairs lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si), etc.) exhibit similar properties.}$
