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 :
