Question

Considering the element $B,Al,Mg$ and $K$, write the correct order of their metallic character.

Answer 1

$K>Mg>Al>B$ represents the correct order of metallic character.
On going from left to right in a period, the metallic character decreases. Thus the order $K>Mg>Al$. On moving down the group, the metallic character decreases.Hence, $B$ is less metallic than $Al$.
