Atomic theory: atomic theory, ancient philosophical speculation that all things can be accounted for by innumerable combinations of hard, small, indivisible particles (called atoms) of various sizes but of the same basic material or the modern scientific theory of matter according to which the chemical elements. The atomic theory the idea that the elements are capable of being split up into very tiny particles was rst evolved by the greeks the word atom comes from the greek word atomos which means indivisible and the idea that the elements are made up of atoms is called the atomic theory.

Well, in terms of atomic chemistry, hank takes us on a tour of the folks that were part of the long chain of other folks who helped us get to these deeper understandings of the world. Modern atomic theory is, of course, a little more involved than dalton's theory but the essence of dalton's theory remains valid today we know that atoms can be destroyed via nuclear reactions but not by chemical reactions.
