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

A

`B gt Al gt Mg gt K`

B

`Al gt Mg gt B gt K`

C

` Mg gt Al gt K gt B`

D

`K gt Mg gt Al gt B`

Text Solution

Verified by Experts

The metallic character of elements decreases from left to right across a period. Thus, the metallic character of Mg is more than that of Al.
The metallic character of elements increases down a group. Thus, the metallic character of Al is more than that of B.
Considering the above statements, we get `K gt Mg`.
Hence, the correct order of metallic character is `K gt Mg gt Al gt B.`

Considering the elements B, C, N and Si , the correct order of their non-metallic character is ?

The correct order of the non - metallic character is :

Atoms of metals have only a few electrons in their valence shells while atoms of non-metals generally have more electrons in their valence shells. Metallic character is closely related to atomic radius and ionization enthalpy. Metallic character increases from top to bottom in a group and decreases from left to right in a period. Metallic character is inversely related to electronegativity. Considering the elements B,C,N and F the correct order of their non-metallic character is

The correct of the metallic character is :
