Question

Que---The valency of group 1 elements Required to answer.



A. Increases with the increase in a
atomic radii


B. Decreases with decrease in atomic radii


C. Remains constant with increase in atomic radii


D.First increases then decreases with increase in atomic radii

​

Answer 1

Answer:

Moving down a group in the periodic table, the number of electrons and filled electron shells increases, but the number of valence electrons remains the same. The outermost electrons in a group are exposed to the same effective nuclear charge, but electrons are found farther from the nucleus as the number of filled energy shells increases. Therefore, the atomic radii increase.
