Question

as the size of an atom increases metallic character

Answer 1

Answer:

The atomic size of elements increases due to addition of new valence shells. Also, metallic property / character increases down the group. This is due to the fact that while moving down the group ionic radii increases so tendency to loose electrons is increased and hence they form Cation
