Atom center of mass, although strictly speaking these particles are believed to be point-like and cannot be said to be rotating. Spin is measured in units of the reduced Planck constant (ħ), with electrons, protons and neutrons all having spin ½ ħ, or "spin-½". In an atom, electrons in motion around the nucleus possess orbital angular momentum in addition to their spin, while the nucleus itself possesses angular momentum due to its nuclear spin. The magnetic field produced by an atom—its magnetic moment—is determined by these various forms of angular momentum, just as a rotating charged object classically produces a magnetic
The History and Adventures of an Atom The History and Adventures of an Atom The History and Adventures of an Atom, by Tobias Smollett, is a novel that savagely satirises English politics during the Seven Years' War. It appears under the guise of a tale from ancient Japan. Pitt the Elder appears as "Taycho", and other politicians, monarchs and nations under a light disguise of made-up names.
