The screening effect of d-electrons is:
The screening effect of d-electrons is:
The correct option is D Less than p-electrons
For this let's discuss penetration effect.
Penetration power can be simply phrased as closeness to the nucleus.
Within a principle quantum number, s is closer to the nucleus to the nucleus than p, d and f.
The correct order of orbitals in a given shell for the penetration effect is s >p > d > f.
Screening effect, also known as the shielding effect, reduces the effect of the nucleus on the outer electrons, i.e., inner electrons act as a shield and reduce the electrostatic interaction between the nucleus and outer most electrons.
Now as we know from the penetration effect that s and p are closer to the nucleus than d, therefore they will shield the d electrons. But within a shell d electrons will not be able to shield the p electrons.
This implies screening effect of d-electrons is less than p-electrons.
