The History of Atomic Theory. A piece by piece progression through the structure of the atom. What is Atomic Theory. Atomic theory states that all matter is composed of discrete units called atoms The Greek word atomos means “indivisible”
A piece by piece progression through the structure of the atom
Any piece of matter can be broken down into smaller pieces.
Therefore, matter is continuous, not discrete.
In between these atoms is empty space
Therefore, matter is discrete, not continuous.

Plum Pudding… yummy…
To visualize, the atom is spread out like this:
If the whole atom were pirate stadium, the nucleus would be your class ring sitting on the 50-yard line
Now, we know that protons, neutrons, and electrons are actually composed of even smaller particles. But that’s another course…
