Why are d Electrons Less Effective in Shielding Nuclear Charge?

Click For Summary
SUMMARY

The discussion centers on the effectiveness of d electrons in shielding nuclear charge compared to s and p electrons. It is established that d electrons exhibit greater azimuthal dependence due to their spherical harmonics, which contributes to their reduced shielding capability. This characteristic leads to increased polarizing power of d electrons. Understanding these differences is crucial for comprehending electron behavior in transition metals.

Why are the d electrons less effective in shielding the nuclear charge than the s or p electrons, and are thus more polarizing?
 
Physics news on Phys.org
I believe it has to do with Spherical Harmonics of the wave equation - there is more azimuthal dependence for the d electrons than p or s.
 
thank you very much!
