The 4d orbital is at a much higher energy level than 4s or 4p. The 3d orbital has a very close energy level to 4s and will alternate depending on its electron state. Just know that it is not 4d because it would not make sense to write 4d before 4s. It just all because of the d orbital's energy level.
