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
If Mg lies above Al ie, Mg is more reactive than Al...
Then why does Al replace Mg from MgO (magnesium oxide)
And is used extract magnesium from magnesium oxide
