- The electron configuration for iron includes the 3d sublevel, which is crucial for its magnetic properties.
Examples
-
Because of the relative magnitudes of the matrix elements of the transitions involved, the molasses light pumps almost all the atoms into one of their outermost two sublevels.
Academic text (1994) -
Researchers are therefore investigating QD systems in which the ground state contains sublevels that can be optically manipulated through an intermediate excited state transition.
Academic text (2002) -
That's the sublevels of quantized in Z direction.
-
The energy of an atom in a given sublevel varies at different locations in the standing wave because the atom's light shift depends on the polarization of the light.
Academic text (1994) -
Coupling raises and splits the degenerate independent-electron levels into sublevels characterized (and labeled) by total spin (1 or 0).
Academic text (1994) -
(A multiplet is an identifiable pattern of spectral lines, arising from electron transitions (jumps) between the sublevels of two energy levels in an atom.)
Academic text (1990) -
For example, a rubidium atom in the m = -3 sublevel has its lowest energy in a region of sigma-polarization; it sees a periodic array of potential wells, with the well minima spaced by lambda/2.
Academic text (1994) -
In the electron configuration of carbon, the 2p sublevel is filled after the 2s sublevel.
-
When the atom is excited, electrons may jump to higher sublevels before returning to their ground states.

Etymology
Sublevel comes from the prefix sub- meaning 'under' and level, so in science it means a smaller level inside a larger one. In atoms a sublevel is a smaller part of an electron shell, like a big floor divided into smaller sections, and the same sub- you see in subway ('under' the ground) helps you remember it is under the main level.
