Models of the Atom
We’ve come a long way since the first atomic theory
proposed by Democritus. With many new discoveries along the way, our understanding of the
atom has also changed over the course of time. In this task, you will analyze several historical
models of the atom.
Part A: Dalton’s Atomic Model
Using what you can recall from this unit, write one or two short paragraphs describing John
Dalton’s atomic model. If needed, search the Internet for descriptions of the model.
