The Atomic Theory states the basic rules that every material follows. It states that everything is made up of tiny particles called "atoms." These atoms vary in many different ways. The differentiations give each atom its own unique properties and allow it to make the substances that we use every day.

The Atomic Theroy has been around for years longer than one would assume. However, in just the recent years , it has been fully accepted and applied to practical uses.

This is an introduction to the general ideas of the Atomic Theory, which should help build an understanding of what material scientists have to consider when studying new particles and making new products.

A quick note before reading: Many of the things described are known to be true, but have no explanation. In some cases scientists understand what happens, but do not know why it happens.
