Question

Give reason.
a. Chemical reactivity of metals increases while moving down in a group.
lo dooroncos while moving from left to right in a period,​

Answer 1

Explanation:

They have a strong tendency to lose this electron and acquire the stable configuration of the nearest noble gas. Thus, the reactivity of alkali metals depend upon their ability to lose electrons. Since their tendency to lose electrons increases down the group hence their reactivity increases down the group
