Atoms are composed of tiny subatomic particles such as electrons, protons, and neutrons. Electrons are the smallest and most mobile particles in the atom and their distribution in the atom’s orbitals determines the properties of the element. This distribution of electrons is called the electron configuration.
The electron configuration of an element is written using the standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence. For example, the electron configuration of sodium is 1s22s22p63s1.
Electron configurations are used for a variety of reasons. They are used to determine the valency of an element (which describes how many bonds it can form with other elements), to predict the properties of a group of elements, and to interpret atomic spectra.

What element has the following electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3?
Electron configurations are an important concept in understanding the properties of elements. By looking at the electron configuration of an element, we can understand the number of electrons present in each of its atomic orbitals and determine the element’s valence. The electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3 is the electron configuration for the element Selenium.
What are Electron Configurations?
Electron configurations refer to the arrangement of electrons in the shells and subshells of an atom. This arrangement is determined by the energy levels of the electrons, and can be written using a standard notation. Each energy level is represented by a principal quantum number (n), and each subshell is represented by an azimuthal quantum number (l). For example, the electron configuration of sodium is written as 1s22s22p63s1.
The electron configuration of an element is important in understanding its physical and chemical properties. Elements with similar electron configurations tend to exhibit similar properties, and the electron configuration of an element can be used to predict its valence. Additionally, electron configurations are used to interpret atomic spectra.
Notation
The electron configuration of an element is written using a standard notation. This notation consists of a sequence of subshells, each labelled with the shell number (given by the principal quantum number), the subshell name (given by the azimuthal quantum number) and the total number of electrons in the subshell in superscript. For example, if two electrons are filled in the ‘s’ subshell of the first shell, the resulting notation is ‘1s2’.
History of Electron Configurations
The notation for the distribution of electrons in the atomic orbitals of atoms came into practice shortly after the Bohr model of the atom was presented by Ernest Rutherford and Niels Bohr in the year 1913. However, it was only in the 1920s that the modern electron configuration notation was developed.
