Throughout the years the Quantum Mechanic model has evolved many times. This evolution has taken place after every major discovery in Quantum Mechanics. The current Quantum mechanic model is by far the most accurate example of an atom and how it works. Currently the model depicts a proton (or more than one depending on the atom) and neutron in the nucleus and a an electron rotating around the nucleus in an energy level, or an estimated path of the electron.
The first person to purpose the existence of atoms was Democritus. Democritus’ had the right idea however the details of his original theory were not quite right. Democritus believed there was a select few elements and the ratio between these elements made up matter. It was free thinking individuals like this that led to the discovery of several theories that aloud atoms to be tested.
François Bacon was one of those individuals. He saw a need for organization in the scientific community. His answer to this was the scientific method. The scientific method was a list of steps that helped organize experiments.
Antoine Lavoisier was a French nobleman that had made a hobby of chemistry. However because of this bored tax collector with a passion we were able to accurately test countless theories. Lavoisier created the “Law of Conservation of Matter,” which stated that no matter could be created or destroyed. This Law caused a flurry of questions, were did this come from and where did that go became a question in every experiment.
Robert Boyle now armed with new scientific knowledge began to concentrate on gases. Boyle declared in 1662 that, “For a fixed amount of gas kept at a fixed temperature, P and V are inversely proportional.” After Boyle many followed in the study of gases. Two scientists who chose to study this were Amedeo Avogadro and Joseph Louis Gay-Lussac. Amedeo Avogadro had hypothesized that Equal volumes of gases, at the same temperature and pressure, contain the same number
