Brief review of Quantum Numbers, Orbitals, and Electron Configurations A moving electron, by virtue of its nearly negligible mass, behaves as a De Broglie matter wave, and this behavior can be described by Schrödinger’s wave function Ψ which, when squared (Ψ 2 ), lends a physical connotation to the probability of the electron’s 3-dimensional location around the nucleus (i.e., its “orbital”) as related to energy (by virtue of the attraction between the electron and the positively-charged nucleus). These different “orbitals” are designated by 3 quantum numbers: n (primary) – designates size and energy of orbital (as related to distance between e - and nucleus) l (angular momentum) – designates orbital shape (the type of orbital: s, p, d, f) m l (magnetic) – designates orbital orientation (how many of each type of orbital)
