The Atomic Model

Who Created It

The first atomic model was created in the year 400 B.C., by a Greek philosopher named Democritus. The atomic model Democritus made was just a round solid ball. The reason Democritus' model was so simple, was because all he knew about atoms was that they were solid, indestructible, and unique. Democritus also did not know about a nucleus or electrons.

Why It's useful

The atomic model is very useful today in studying atoms. The atomic model helps us to understand how an atom works, and also why it is important. Models make it easy to examine things that usually need a very powerful microscope to see.
