Question

How do the atomic radius and metallic character of elements vary as we move down a gropu and from left to right in period?

Answer 1

Atomic radius has direct connection with atomic size. And atomic size decreases on moving from left to right in a group but increases on moving down a group.
Thereby atomic radius decreases on moving left to right but increases on moving top to bottom.

Metallic character is dependent on atomic size.
Therefore, metallic character decreases on moving left to right but increases on moving down a group...
