Early atomic theory although the idea of the atom was first suggested by democritus in the fourth century bc, his suppositions were not useful in explaining chemical phenomena, because there was no experimental evidence to support them. In this lesson, students will define the terms theory and model as well as describing the development of the modern atomic theory as a result of the contributions of democritus, thomson, dalton, and rutherford.
