AtomicThe general meaning of "atomic" is "irreducible". That is, reduced to the smallest possible part. It has more specific meanings in several contexts: * In chemistry, chemical atoms are grouped by type in the periodic table and consist of particles as described by particle physics. * In computer science, an atomic operation is one that cannot be subdivided. Or more specifically, an operation that always completes as a whole, or doesn't complete at all. See atomic (computer science).
