Atomic Theories Comparison
The idea of an atom -- the smallest particle of matter -- has intrigued mankind since the beginning of civilization. Throughout the centuries the "view" of the atom has changed. New ideas, and new technologies have influenced the model of the atom. This view of the atom is still a Theory and therefore it is still subject to change. The modern model of the atom is called the Quantum Model and you will study this model in future grades (Grade 11 and 12 Chemistry & Physics). The chart on the website linked below summarizes the various atomic models that have been developed during the course of history.
