Question

What is periodicity. How metallic nature can change in a group and period​

Answer 1

Answer:

Metallic character increases down a group due to increase in atomic size. Thus, the outermost electrons are farther away from the nucleus and therefore can be lost easily. Hence, the electropositive character or metallic character increases.

Answer 2

The metallic character increases as you go down a group.As we move across the periodic table,there is an increasing tendency to accept electrons(non-metallic) and a decrease in the possibility that an atom would give up one or more electrons
