elektronitilaa
Elektronitila is a term used in physics and chemistry to describe the quantum state of electrons bound to an atom, ion, or molecule. It encompasses the energy, spatial distribution, angular momentum, and spin of the electrons, and can refer to a particular configuration of occupied orbitals or to the ensemble of possible states of a system. The electronic state governs many properties, including energy levels, spectra, magnetism and chemical behavior.
Occupancy of electronic states follows several well-established rules. The Pauli exclusion principle allows at most two
Electronic configurations are commonly written to denote which orbitals are occupied. Examples include hydrogen: 1s1; carbon:
In molecules, electrons fill molecular orbitals formed from linear combinations of atomic orbitals. Valence electrons determine
