Lesson 1: The Nature of Atoms
Overview:
We will start our journey from a historical approach dating back to the times of the Greeks. In their attempt to explain everything around them, they proposed to continue cutting any material until reaching a point that the material becomes uncuttable. Today we call this uncuttable material the atom. With the history of the atom, there has been many theories proposed as a working model, yet time and time again we continue to learn something new about this thing called the atom, thus needing to expand existing theories.
In this lesson we will explore the different models proposed of the atom, and find out what it means to be an element.
