  • question_answer
    Mg and Li are similar in their properties due to:

    A) same e/m ratio

    B) same electron affinity

    C)  same group

    D)  same ionic potential

    Correct Answer: D

    Solution :

    The elements of second period resemble in many respect to those elements of third period which are diagonally opposite to them (diagonal relation) Diagonally related elements have nearly the same value of electronegativity polarising power Ionic potential \[\left[ \frac{\text{ionic}\,\text{charge}}{{{\text{(atomic}\,\text{radius)}}^{\text{2}}}} \right]\]
