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
Ariel Atom Atom 4. The limited production Ariel Atom 500 V8 featured a V8 engine. The all new Ariel Atom 4 is the latest Atom featuring a new turbocharged 2.0l engine that is used in the Honda Civic Type R with 3-stage boost. The Ariel Atom features a prominently visible chassis (i.e., an exoskeleton, no roof or windows, a small optional windscreen) and a drag coefficient of 0.40. The Atom began as a student project by Coventry University transport design student, Niki Smart. Known then as the LSC (Lightweight Sports Car), it was developed at the university in 1996 with input and
