Electron configuration refers to the arrangement of electrons in various energy levels and orbitals within an atom. It follows the principles of quantum mechanics and the Aufbau principle, Pauli exclusion principle, and Hund's rule. The electron configuration determines the chemical properties of elements as it governs their reactivity, bonding behaviour, and the formation of chemical compounds. Elements with similar electron configurations exhibit similar chemical properties and tend to form similar types of chemical bonds. The electron configuration provides insights into an element's stability, ionisation potential, and its tendency to gain or lose electrons.
