An orbital describes a probability region for finding an electron at a certain energy level, distance, and orientation as related to the atomic nucleus. Orbitals are described by a set of quantum numbers that describe their location shape and electron...

In physics, orbital motion is the either a motion of a planet in a planetary orbit, or a motion of an electron around the nucleus of an atom, or any other motion of parts of a bound system. In quantum mechanics, orbital motion contributes to the angular...
