_______________________
Li+ has lesser atomic size than Mg2+
because :
Li+ ( electronis cofiguration = 1S2 ) which means it has 1 energy shells .
While...
Mg2+ ( electronis cofiguration = 1S2 , 2S2 , 2P6 ) which means it has 2 energy shells .
Therefore Mg2+ has larger atomic size than
Li+ due larger atomic radius.

Explanation:
Thus, from triangle DEC, we can say that cosθ=DECD . From the distance formula, we can say the that the length of DE is 12√3 and CD is √32 . Therefore, the angle between two faces is cos−113 . So, the correct answer is “Option B”.
