Electron Configuration Chart for All Elements in the Periodic Table

There are 118 elements in the periodic table. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. This article provides you with an electronic configuration chart for all these elements.

Theoretical Basis

The electronic configuration of each element is decided by the Aufbau principle which states that the electrons fill orbitals in order of increasing energy levels. The equation is:
1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p 

The concept of electronic configuration has replaced the older concept of valency and valence electrons. It involves the specific arrangement of electrons in shells and sub-shells of Bohr’s atomic model. This model has been widely accepted, and according to it, each atom has shells, which further have subshells. The shells are labeled K, L, M, N, and so on, from the innermost to the outermost shell.

Each shell has subshells that are named for the type of emission lines produced from different states of angular momentum. They stand for sharp (S), principal (P), diffuse (D), and fundamental (F). The subshells have a distinct shape and configuration, in which the electrons move freely. Each shell and subshell have a limitation on the amount of electrons that it can carry. The maximum electrons that can be carried by the sub-shell S is 2, by P is 6, by D is 10, and the F sub-shell can carry 14. This decides the electron capacity of the shells. The K shell contains a 1s subshell hence it can carry 2 electrons, the L shell has 2s and 2p, and can carry 8 electrons. The M shell contains 3s, 3p, and 3d, and can carry 18 electrons. The N shell containing 4s, 4d, 4p and 4f, can carry 32 electrons. Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table.
