Considering the elements B, Al, Mg, and ...

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

A

`BgtAlgtMggtK`

B

`AlgtMggtBgtK`

C

`MggtAlgtKgtB`

D

`KgtMggtAlgtB`

Text Solution

Verified by Experts

(d) `K gtMggtAlgt B`. This is because metallic character decreases across a period. Therefore, the metallic character of Al, Mg and K will be in the order `K gt Mggt Al`. Further, metallic character increases on moving down a group. Therefore, B should be less metallic than Al
