Both lithium and magnesium display several similar properties due to the diagonal relationship , however, the one which is incorrect is

Li resembles Mg due to diagonal relationship which is atributed to:

Which of the following property of lithium and magnesium is not related to their diagonal relationship ?

Diagonal Relationship Of Lithium With Magnesium

Which of the following properties describes the diagonal relationship between both boron and silicon ?

Lithium and magnesium exhibit diagonal relationship because

Lithium and beryllium, the first members of alkali metals group and alkaline earth metals group, show anomalous behaviour due to the small sizes of their atoms and ions, high ionisation enthalpies, high polarizing power and absence of vacant d-orbitals in their valence shell. Lithium resembles magnesium while beryllium resembles aluminium due to diagonal relationships. Lithium is the only alkali metal which forms nitride directly. Why?
