Structure of Matter
The idea that matter is made up of minute particles called atoms dates back to the ancient Greeks. According to Greek philosopher Democritus, given a piece of object or substance, say a piece of yam, can be cut into smaller bits, until eventually a smallest piece of that substance would be obtained which could not be further subdivided. Those indivisible piece are called Atoms. The atomic theory of matter assumes that alkl matter is made up of tiny particles called atoms and that thgese are at all times in a rapid state of motion.
