WebJun 29, 2024 · 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. pho 85 noodle house rogers arWebNo Comments. The screening effect of d- electrons is less than p – electrons. In general, d and f electrons have a poor shielding effect compared to s and p electrons. This is because s and p electrons are close to the nucleus whereas d and f electrons are more diffused (away from the nucleus). Hence, the correct option is D. pho 888 austin
