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

During a period, the metallic nature of the components diminishes as we move from left to right in the period. As a result, Mg > Al.

With each group we progress below, the metallic aspect of the components becomes less prominent. As a result, Al > B.

It can be concluded from the two assertions above that K is greater than Mg.

As a result, K > Mg > Al > B
