The metallic character of group 14 elements:
Decreases from top to bottom in group
Remains same for all elements of group
Increases from top to bottom in group
Decreases and then increases
The metallic character of group 14 elements increases from top to bottom because removal of electron becomes easier on moving down the group.
It is observed that the metallic character of an element increases down a group. Then how can we determine how the non metallic character of an element increases?
