Metal used in flash photography is:
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
Question 17 Arrange the following elements in the order of their decreasing metallic character Na, Si, Cl, Mg, Al (a) Cl > Si >Al > Mg >Na (b) Na >Mg >Al >Si > Cl (c) Na > Al > Mg > Cl > Si (d) Al > Na> Si > Ca> Mg
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
