Question -

 Considering the elements B, Al, Mg, and K, the correct order of their metallic
character is :

(a) B > Al > Mg > K                       (b) Al > Mg > B > K
(c) Mg > Al > K > B                       (d) K > Mg > Al > B



Answer -

(d) K > Mg > Al > B
Reason:
As we move from left and right in a period the metallic character of the elements decreases. Thus, Mg > Al.
As we move down from a group the metallic character of the elements decreases. Thus, Al > B.
From the above two statements, it can be stated that K > Mg.
Thus, K > Mg > Al > B
