Electron Configurations
Do we have to write 4s after 3d in electron configurations? And why is the energy of the 3d orbital less than the 4s orbital only if it is partially filled?

Re: Electron Configurations
Yes with Dr. Lavelle we do need to write 3d before 4s because 3d actually comes before 4s in electron configuration. 3d is in 3rd principle energy level and 4s is in 4th principle energy level. I'm not too sure about the second part of the question.

Re: Electron Configurations
You always remove 4s electrons first before 3d because the 4s has electrons that are on the outer shell, so these electrons are lost first.

Re: Electron Configurations
In what scenario would a valence configuration be used over an electron configuration?

Re: Electron Configurations
4s is written after 3d if this level appears in the configuration. It was experimentally proven that 4s has a lower energy level then 3d
