The electron configuration, valence electrons, and Lewis symbols are crucial concepts in understanding the properties and bonding behavior of atoms.
Electron Configuration: The electron configuration of an atom describes the arrangement of electrons in its orbitals. It follows the Aufbau principle, Pauli's exclusion principle, and Hund's rule.
Valence Electrons: Valence electrons are the electrons in the outermost shell of an atom, determining its chemical properties and bonding behavior.
Lewis Symbols: Lewis symbols represent the valence electrons of an element using dots around the element's chemical symbol.
