Metallic character of group 15 elements

Metallic character:

The elements of group 15 are less metallic than group 14 elements. However, metallic character increases on moving down the group.

 Reason:

Due to the increased nuclear charge and higher electronegativity, the elements of the group 15 are less metallic than the corresponding elements of  group 14. As on moving down the group, atomic size increases and electronegativity increases the valence electrons become loosely held and are lost more readily. Therefore, on moving down the group metallic character increases. In this family, N and P are non metals, As and Sb are metalloids While Bi is a typical metal.
