Question

How does the shielding phenomenon affect the relative atomic sizes of elements in the same group?

A. An increase in the degree of shielding causes a decrease in atomic size.

B. An increase in the degree of shielding causes an increase in atomic size.

C. Shielding has no effect on relative atomic size within a group.

D. Shielding does not have an affect on the sizes of atoms.

Answer 1

Is B the correct answer?

Answer 2

Yes, an increase in the degree of shielding causes an increase in atomic size because if inner electrons shields the attractive force of nucleus the force experienced by the electron is less and it can slightly expand and size increases.

Answer 3

An increase in the degree of shielding causes an increase in atomic size.B is right

Answer 4

THANKS!
