Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons.. An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. In doing so, we obtain three quantum numbers (n,l,m l), which are the same as the ones obtained from solving the Schrodinger's equation for Bohr's hydrogen atom. Note that when writing the electron configuration for an atom like Fe, the 3d is usually written before the 4s.
