WebAccording to the Democritus atomic theory, atoms of different sizes and shapes were in continuous motion within a void. During this, they banned and collided with each other, rebounding or joining. So changes in matter happened due to the combination or disassociation of the atoms. 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. Ancient Greek philosophers called these hypothetical ultimate particles of matter atomos, a word which mean…
