Q. In the Periodic Table metallic character of elements shows one of the following trend
A) Decreases down the group and increases across the period
B) Increases down the group and decreases across the period
C) Increases across the period and also down the group
D) Decreases across the period and also down the group
Explanation
(b)
Metallic character atomic size
$\frac{1}{nuclear\ charge}$ (for a period only)
Metallic character decreases across a period from left to right because atomic size decreases.
In a group from top to bottom, metallic nature increases due to increase in atomic size.
