They're not electrons, but angular momenta in these entities can cancel by Russell-Saunders coupling
They're not electrons, but angular momenta in these entities can cancel by Russell-Saunders coupling. A set of these entities has subscripts "x squared," "xz," "yz," "xy," and "x squared minus y squared." One of these entities is shaped like a torus surrounding a dumbbell. Madelung's rule gives the energies of these things but does not explain their unusual configuration in palladium, chromium, and copper. The Pauli exclusion principle and (*) Hund's rule are the basis for the Aufbau principle for these entities. The second, or "azimuthal" quantum number classifies them into s, p, d, and f varieties. For 10 points, name these regions of an atom that can be occupied by up to two electrons.
