As orbitals correspond to number of the subshell. 1 corresponds to s orbital. 2 corresponds to 2s 2p . 3 corresponds to 3s 3p 3d. 4 corresponds to 4s 4p 4d 4f.

For ahydrogen-like electron system, the energies of the subshells depend only on theprincipal quantum number. 1s < 2s = 2p <3s = 3p = 3d < 4s = 4p = 4d = 4f < However, for a multielectron atom or ion (an atom or ion containing a nucleus andmore than one electron), the energies of the subshells are no longer the same becauseof the various electron-electron interactions and generally follow the order.

The arrow goes through 1s first, then 2s, then 2p & 3s, then 3p & 4s, then 3d, 4p, & 5s, and so on. Some people find it easier to use the periodic table as the “road map”: As you move through the elements in order by atomic number, you are moving through the sub-levels from lowest to highest energy.
