The arrangement of electrons in different shells and sub-shells is known as the electronic configuration of a particular element. The electronic configuration diagram represents an element in its ground state or stable state. There are a set of rules to remember while distribution off electrons in different orbits.

Electronic Configuration of an Atom
Electronic configuration is the distribution of electrons into orbitals of an atom. It is also known as the electronic structure of an atom. The electronic configuration of an atom is important as it determines the chemical and physical properties of an element.
The electronic configuration of an atom is written using the Aufbau principle, Pauli exclusion principle, and Hund's rule. These principles help in determining the order of filling of electrons into different energy levels and orbitals.
Aufbau Principle
The Aufbau principle states that electrons fill the lowest energy orbitals first before moving to higher energy orbitals.
Pauli Exclusion Principle
The Pauli exclusion principle states that each electron in an atom must have a unique set of quantum numbers. This means that no two electrons in an atom can have the same four quantum numbers.
Hund's Rule
Hund's rule states that electrons occupy orbitals singly before pairing up. This means that electrons in a subshell will occupy different orbitals with the same energy level before pairing up.
Representation of Electronic Configuration
The electronic configuration of an atom is represented using the notation of the noble gas configuration. This means that the electronic configuration of an atom is written as the symbol of the noble gas element that precedes it in the periodic table, followed by the electronic configuration of the remaining electrons.
For example, the electronic configuration of sodium is written as [Ne] 3s1. This means that the first ten electrons of sodium occupy the same electronic configuration as neon, and the remaining electron occupies the 3s orbital.
Conclusion
In summary, the electronic configuration of an atom is the distribution of electrons into orbitals, and it is determined by the Aufbau principle, Pauli exclusion principle, and Hund's rule. The electronic configuration of an atom determines its chemical and physical properties and is represented using the noble gas configuration notation.
