It is important as a scientist to know the major people involved in discovery and understand the experiments performed which led to our current understanding of the atom. Names and achievements of the scientists who have helped to lay the foundation of our knowledge are important to know to allow for a historical perspective of our understanding. With the discovery of the subatomic particles such as the electron, proton, and neutron we can explain isotopes, bonding, and many other atomic properties. Further, knowledge of isotopes helps us to understand why atoms do not have integral masses - the measured atomic mass of an element is a weighted-average atomic mass of the
