Why do we write 3d before 4s?

Re: 4s before 3d Electrons usually enter the 4s orbital before the 3d because the 4s is initially lower in energy. However, from Scandium and onwards, the 3d orbital of transition metals actually becomes lower in energy than the 4s, which is why we write 3d before 4s in the configuration. Oct 25, 2017

Electrons can exist between shells. ... It takes a finite time for an electron to make a transition. They just can't stay between the shells, because there is no energy eigenstate there, and only energy eigenstates are stationary.

Why is the 4s orbital lower in energy than 3d?

In the electronic configuration of transition metal we first fill 4s-orbital since the energy of 4s-orbital is less than the 3d-orbital due to screening of nucleus charges. But when the 3d-orbital is filled up with electron after having been filled up 4s-orbital, the energy of 3d orbital is found to be reduced.
