atomic spectrum
( in spectroscopy: Angular momentum quantum numbers )
...called the orbital quantum number, must be less than the principal quantum number n, which corresponds to a “shell” of electrons. Thus, l divides each shell into n subshells consisting of all electrons of the same principal and orbital quantum numbers.

electronic configuration
( in chemical bonding: Quantum numbers )
...in a shell of principal quantum number n are limited to the n values 0, 1, 2, . . . , n − 1, and the value of l of an orbital in a given shell determines the subshell to which that orbital belongs. It follows from the allowed values of l that there are n subshells in a shell of principal quantum number n. As will be explained, there...

( in spectroscopy: Relation to atomic structure )
...resulting in a series that appears inverted as compared with the hydrogen series. Also, the different angular momentum states for a given shell cause energy sublevels within each shell; these subshells are labeled by Roman numerals according to their energies.

ionic bonding crystal
...(oxygen, sulfur, selenium, and tellurium) need two electrons to fill their outer p-shell. (Electron shells are divided into subshells, designated as s, p, d, f, g, and so forth. Each subshell is divided further into orbitals.) Two electrons are transferred from the cations to the anions, leaving each with a closed shell. The alkaline earth...

islands of stability transuranium element
...of which are thought to be magic numbers. Isotopes in this region, which theoretically should have significantly longer half-lives than the neighbouring known heavy isotopes, are sometimes termed superheavy elements (SHE). There is also evidence for subshells (regions of somewhat increased stability) at Z = 108 and N = 162.
