Question

What is the relationship between metallic character and the size of an atom?

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.

Answer 2

Answer:

the atoms decreases

Explanation:

The atomic size of an atom is the distance between the centre of its nucleus and its outermost electron shell. In the Periodic Table, on moving from the left to the right in a period, the atomic size and metallic character of the atoms decreases while, the non-metallic character increases.
