Question

will the reactivity of metals and that of non metals remain the same or decrease or increase down the group.... plzz give reason
​

Answer 1

Answer:-

The reactivity of metals and that of nonmetals increases for the metals and decreases for the non metals down the group.

The nuclear charge experienced by the valence electrons decreases down the group as the outermost electrons are farther away from the nucleus.

The metallic character increases down the group, as they can lose electrons easily because of the reason given in the second paragraph.

Similarly, non non metallic character decreases down the group as it is hard for them to gain electrons because again of the reason given in second paragraph.
