electronic configuration. A list showing how many electrons are in each orbital or subshell. There are several notations. The subshell notation lists subshells in order of increasing energy, with the number of electrons in each subshell indicated as a superscript. For example, 1s2 2s2 2p3 means '2 electrons in the 1...
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s2 2s2 2p6. Electronic configurations describe electrons as each moving independently in an orbital, ...

Specific distribution of electrons in atomic orbitals of atoms or ions.
The disposition of electrons among the orbitals of an atom. The electron configuration of the outer shells, in particular, is a key determinant of the chemical properties of the atom. Each electron in an atom is associated with four characteristic quantum numbers, which are interrelated. These are...
