Question

The properties of lithium are similar to those of $Mg$. This is because

• A. both have nearly the same size
• B. the ratio of their charge to size is nearly the same
• C. both have similar electronic configurations
• D. both are found together in nature

Answer 1

Answer: (B)

The properties of lithium are similar to those of Mg because they are having diagonal relationship. The elements having diagonal relationship show similar properties and the reason is because the both of them will have similar electronegativity and polarising power i.e. charge per size ratio of both the elements are nearly the same.
