What is the Particulate Model of Matter? Based on the evidence gathered from observations and experiments, scientists proposed a model which explains the nature of matter. This model is called the Particulate Model of Matter. Tje Particulate Model of Matter states that matter is made of tiny discrete particles, which are in constant and random motion. About 2500 years ago, the greek philosopher, Democritus (460 B.C. - 370 B.C), proposed that if one were to break up matter into smaller and smaller pieces, there would come to a point when it could no longer be divided further. He called this smallest indivisible bit of matter 'atom'. On the other hand, another famous philosopher, Aristotle (384 B.C - 322 B.C), proposed that matter has a continuous composition and that it can be broken down into smaller and smaller pieces forever. After the Brownian Motion ( particles in pollen grains that moved constantly and randomly in no specific directions ) was explained by Elbert Einstein and demonstrated by Jean Baptiste Perrin, in other words, Democritus' proposal that matter is made up of tiny particles is indeed right.
