Electron Configurations and Orbital Diagrams KEY ... Write the electron configuration (full, and in core notation) for the following ions: 1.-1Br +3 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 6 [Kr], [Ar] 3d 10 4s 2 4p 6 ... Microsoft Word - Electron Configurations and Orbital Diagrams key Author:
Electron orbital diagrams and written configurations tell you which orbitals are filled and which are partially filled for any atom. The number of valence electrons impacts on their chemical properties, and the specific ordering and properties of the orbitals are important in physics, so many students have to get to grips with the basics.
It also shows you how to find the 4 quantum numbers for an electron and how to write the electron configuration in addition to how to write the orbital notation or fill in the arrows in the ...
For atoms, the notation consists of a sequence of atomic subshell labels (e.g. for phosphorus the sequence 1s, 2s, 2p, 3s, 3p) with the number of electrons assigned to each subshell placed as a superscript. For example, hydrogen has one electron in the s-orbital of the first shell, so its configuration is written 1s 1.
A molecular orbital diagram, or MO diagram, is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the linear combination of atomic orbitals (LCAO) method in particular.
Orbital Diagrams. Many times it is necessary to see all the quantum numbers in an electron configuration, this the purpose of the orbital diagram. In addition to listing the principle quantum number, n, and the subshell, \(\ell\), the orbital diagram shows all the different orientations and the spin of every electron.

Electron configuration notation is a shorthand version of the information contained in orbital diagrams. The squares and arrows are eliminated and replaced with the name of each occupied level, sub-level and a superscript indicating the number of electrons present in that sub-level.
The electron configurations and orbital diagrams of these four elements are: The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3 s orbital, giving a 1 s 2 2 s 2 2 p 6 3 s 1 configuration.
