Question

Compare alkali metals and homework agents with respect to their valency atomic size and

Answer 1

do you mean alkali metals and halogens??

alkali metals have valency 1 and halogens have valency of 1 as well.

the no of valence electrons in lkali metals is 1 while that of halogens is 7.

alkali metals have larger atomic radii than the halogens as atomic radius decreases along the period the nuclear charge increases.

hope this helps!
