Question

Screening effect of d electrons is equal to the f electron

Answer 1

Answer:

Here is the answer to your question:

d orbital is double doumb bell shaped and comes after p orbital.

f orbital has diffused shape and exists next to d orbital.

Since, shielding effect is defined as a reduction in the effective nuclear charge on the electron cloud, due to a difference in the attraction forces of the electrons on the nucleus. If the electron is in s shell, it means it is nearest to nucleus and if in f shell, it means it is farthest from nucleus. Since, atomic shielding spends on electron density in a shell and electron density is very less for d and f shells, hence it has poor shielding effect as compared to s and p shells.
