And filling of the electrons for writing the electronic configuration of the elements is done according to the Aufbau rule, Pauli’s exclusion principle and Hund’s rule. Aufbau rule states that the order of filling various subshells by means of increasing order of energy levels using (n+1) rule.

The electron configuration for any element may be found by clicking on that element in the periodic table. The first exception to the above scheme that is encountered is chromium, where the fifth 3d electron state is occupied instead of the second 4s state. Copper is also an exception, filling all 10 3d states rather than the second 4s state.
So, for example, if we wanted to know the electron configuration for sodium (atomic number 11), we start at the top left and follow that arrow to 1s2 (we can only add two electrons to an "s" orbital).(See orbital list in the lower right of the graphic). Electron Configurations - Solutions Note: The electron configurations in this worksheet assume that lanthanum (La) is the first element in the 4f block and that actinium (Ac) is the first element in the 5f block.

An Introduction to Electron Configurations. Electron Configuration An electron configuration is a description of electron arrangement within an atom, which indicates both population and location of electrons among the various atomic orbitals. General Rules for Electron Configurations 1. Electrons occupy orbitals of the lowest energy available. 2. •To determine the electron configuration of any of the first 38 elements of the periodic table •To determine the identity of an element from its electron configuration •To complete an orbital diagram using arrows to represent electrons
In the modern periodic table, elements are in order of atomic number in periods and groups. Electronic configurations model how electrons are arranged in atoms. The element is helium. To write an electron configuration: 1. Determine the total number of electrons to be represented. 2. Orbitals are considered to be in the same shell if they have the same first number (no matter in what order filling is done). 3. An atom will gain or lose electrons in order to have eight electrons in its outer shell.

The chemical properties of the elements reflect their electron configurations. For example, helium, neon and argon are exceptionally stable and unreactive monoatomic gases. Helium is unique since its valence shell consists of a single s-orbital. The other members of group 8 have a characteristic valence shell electron octet (ns 2 + np x 2 + np ...
- Orbitals are filled in the order of increasing n + l; Where two orbitals have the same value of n + l, they are filled in order of increasing n. No two electrons in the atom will share the same four quantum numbers n, l, m, and s. This means that the two electrons must have opposite (paired spins).
- Add electrons to the sublevels in the correct order of filling. Add two electrons to each s sublevel, 6 to each p sublevel, 10 to each d sublevel, and 14 to each f sublevel. To check your complete electron configuration, look to see whether the location of the last electron added corresponds to the element's position on the periodic table.

Electron configuration order of elements

When a single electron is added to a gaseous atom, it forms a monovalent anion and the enthalpy released is called the first electron gain enthalpy. However, when we add the second electron to the negatively charged ion, this addition of electron will be strongly opposed due to the coulomb forces of repulsion. Electron configurations of elements beyond hassium (element 108), including those of the undiscovered elements beyond oganesson (element 118), are predicted.
