Question

How does the chemical reactivity of alkali metals vary on going down in group 1 of the periodic table​

Answer 1

Answer:

Hyyy

Explanation:

The reactivity of Group 1 elements increases as you go down the group because: ... the outer electron gets further from the nucleus as you go down the group. the attraction between the nucleus and outer electron gets weaker as you go down the group - so the electron is more easily lost.
