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
Captain Atom Captain Atom himself when he first became Monarch. Mon-El appears and helps Captain Atom escape, taking him to the Justice League's satellite, where the League members declare that they are going to bring him to justice for his actions as Monarch. After a struggle with the League, Captain Atom tells them what he can remember. The League reminds him he was a hero who once saved the planet.
