001 - Elements and Molecules
In this video Paul Andersen explains how elements and molecules are made of atoms. In a pure sample of a pure substance the average mass remains the same. If more than one atom is found in a molecule the ration of average masses remains the same. If two elements have the same atoms but differ in arrangement the ratio of average masses will vary.
