Wilhelm Roentgen. Atomic theory is the scientific theory that matter is composed of particles called atoms.Atomic theory traces its origins to an ancient philosophical tradition known as atomism.According to this idea, if one were to take a lump of matter and cut it into ever smaller pieces, one would eventually reach a point where the pieces could not be further cut into anything smaller.
