WebApr 29, 2012 · As I understand this, there are basically two effects at work here. When you populate an $\mathrm{s}$-orbital, you add a significant amount of electron density close to the nucleus.This screens the attractive charge of the nucleus from the $\mathrm{d}$-orbitals, making them higher in energy (and more radially diffuse).The difference in energy … WebThese elements were selected for two reasons. One, electron configurations for these elements are often found mistakenly written by the students, both for atoms and ions. Two, most students still failed to write the correct configuration for Chromium and Copper atoms, and eventually this will lead to the configuration for their ionic form.
