Electron configuration describes the distribution of electrons in an atom's orbitals, providing insight into an element's chemical properties and reactivity. It follows the principles of the Aufbau principle, Pauli exclusion principle, and Hund's rule to determine the most stable arrangement of electrons in an atom's electron shells.

The Aufbau principle is a fundamental concept in chemistry that describes the order in which electrons fill atomic orbitals, starting from the lowest energy level to higher levels. It is crucial for understanding the electronic configuration of elements and the periodic table's structure.

Aufbau principle

The Pauli Exclusion Principle, formulated by Wolfgang Pauli in 1925, states that no two fermions can occupy the same quantum state simultaneously within a quantum system. This principle is fundamental in explaining the structure of atoms and the behavior of electrons in atoms, leading to the diverse properties of matter.

Pauli exclusion principle

Hund's rule states that electrons will fill degenerate orbitals singly and with parallel spins before pairing up, to minimize electron-electron repulsions and maximize total spin. This principle is crucial for determining the ground state electron configurations of atoms and understanding their magnetic properties.

Hund's rule

stable arrangement of electrons

Electron shells are regions around an atom's nucleus where electrons are likely to be found, organized into energy levels that determine an atom's electron configuration and chemical properties. These shells fill with electrons in a specific order, following the principles of quantum mechanics and the Pauli exclusion principle, which influences an element's placement in the periodic table and its reactivity.
