Question:
The set representing the correct order of ionic radius is:
Li+>Be2+>Na+>Mg2+
Na+>Li+>Mg2+>Be2+
Mg2+>Be2+>Li+>Na+
Li+>Na+>Mg2+>Be2+
Solution:
The ionic size of an ion increases from top to bottom and decreases from left to right side of the periodic table. The ionic radius of given ions is mentioned below.
Na+=1.02A0
Be2+=0.39A0
Mg2+=0.72A0
Li+=0.76A0
