Question

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

Metallic character propto atomic size propto (1/nuclear text 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.

Q. In the periodic table metallic character of elements shows one of the following trend:

decreases down the group and increases across the period

increases down the group and decreases across the period

increases across the period and also down the group

decreases across the period and also down the group

decreases down the group and remains constant across the period

Metallic character $\propto$ atomic size $\propto \frac{1}{n u c l e a r c ha r g e}$ (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.
