read the following passage.
the word "atom" was coined by democritus, who, unlike aristotle, believed that matter can be divided only until we get the smallest "indivisible particle." several years later based on macroscopically observable experimental results, dalton proposed that all matter is composed of atoms. many postulates of atomic theory as proposed by dalton were later rejected by jj thompson, who has to his credit the discovery of sub atomic particles like electrons.
use information from the passage to justify whether the characteristics of reliable scientific explanations are present in the development of the atomic theory.
