From group 1 to the noble gases, how does valency change?
ARises 1 to 4, then falls to 0
BFalls steadily from 8 to 1
CRises steadily from 1 to 8
DStays at 1 for all groups
Answer & Solution
Correct answer: A. Rises 1 to 4, then falls to 0
Valency climbs from 1 to 4 at group 14 and then falls as atoms need fewer electrons, reaching 0 at the noble gases.
