    Which is responsible for the diagonal relation of lithium with magnesium?

    A)  Less ionic radii

    B)  High polarizing power

    C)  Approximately equal electronegativity and affinity

    D) All of the above

    Correct Answer: D

    Solution :

    Diagonal relation of lithium with magnesium is due to following factors (i) very small size of lithium (ii) higher polarising power of \[L{{i}^{+}}\] (iii) approximately equal electronegativity and affinity (iv) non availability of d-orbitals in its valence shell
